The Archetypes of Staff Engineers: How to Excel and When Your Business Needs One

As engineering teams grow, so does the need for leadership that isn’t purely managerial. Enter the Staff Engineer—a senior individual contributor who shapes technical strategy, solves complex problems, and drives impact without necessarily managing people.

However, not all Staff Engineers operate in the same way. Their roles typically fall into distinct archetypes, each contributing to the organisation in different ways. Understanding these archetypes can help businesses decide when they need a Staff Engineer and guide engineers aspiring to grow into these roles.

Additionally, as engineers progress beyond Staff level, roles such as Staff+, Principal, and Distinguished Engineer offer increasing influence, from team-wide to company-wide technical leadership. Let’s explore how these levels align.

The Four Common Staff Engineer Archetypes

1. The Tech Lead – Guiding Execution

This archetype drives technical execution, ensuring projects are well-architected and delivered efficiently. They work closely with teams to set technical direction, review critical code, and remove roadblocks.

Signs You Need One:

• Engineering teams struggle with execution and technical direction.
• Projects are frequently delayed due to unclear architecture or lack of leadership.
• The team lacks a central figure to balance business priorities with technical feasibility.

How to Excel in This Role:

• Balance high-level technical vision with hands-on implementation.
• Prioritise effectively—know when to ship and when to refactor.
• Mentor engineers to raise the team’s overall execution quality.

⏩ Common at: Staff Engineer level, sometimes progressing into Principal Engineer

---

2. The Architect – Designing Scalable Systems

The Architect focuses on long-term technical strategy, ensuring that systems scale, remain maintainable, and avoid unnecessary complexity.

Signs You Need One:

• Your system is experiencing growing pains due to ad-hoc architectural decisions.
• There’s an increasing need for consistency across services and platforms.

How to Excel in This Role:

• Stay hands-on enough to understand implementation challenges.
• Build pragmatic, scalable solutions rather than over-engineered abstractions.
• Communicate architectural decisions clearly, ensuring buy-in from teams.

⏩ Common at: Staff+ and Principal Engineer level

---

3. The Solver – Untangling Complexity

The Solver thrives on deep technical challenges—debugging mysterious failures, optimising performance, and solving the hardest engineering problems.

Signs You Need One:

• Your team frequently faces complex, high-stakes technical issues that block progress.
• There’s no clear owner for solving difficult debugging or performance challenges.
• Technical debt and deep system issues are piling up.

How to Excel in This Role:

• Dive deep into problems without getting lost in analysis paralysis.
• Document solutions to avoid repeated issues.
• Share knowledge to help the team develop stronger debugging and problem-solving skills.

⏩ Common at: Staff+ Engineer level, often progressing into Distinguished Engineer

4. The Right-Hand Engineer – Strategic Partner to Leadership

This archetype operates at the intersection of business and technology, working closely with executives and engineering leaders to align technical investments with company goals.

Signs You Need One:

• Engineering and business teams struggle to align priorities.
• You need a technical leader who can provide clarity to leadership without diluting technical realities.
• Scaling the organisation requires a mix of technical and strategic thinking.

How to Excel in This Role:

• Develop a deep understanding of business goals and constraints.
• Build trust with leadership by providing clear, actionable technical insights.
• Make strategic trade-offs that balance speed, quality, and scalability.

⏩ Common at: Principal and Distinguished Engineer level

---

Where Do Staff+, Principal, and Distinguished Engineers Fit?

As engineers progress beyond the Staff Engineer role, their influence expands:

• Staff Engineer – Focuses on guiding execution, resolving technical challenges, and influencing a single team or a few teams.
• Staff+ Engineer – An informal term covering late-stage Staff Engineers who are on the path to Principal, influencing broader technical areas.
• Principal Engineer – Operates across multiple teams, driving technical strategy and architecture at an organisational level.
• Distinguished Engineer – A rare, high-impact role with influence across the entire company, setting technical vision and solving problems at a global scale.

In many companies, Staff Engineers start by excelling in one of the archetypes above, while Principal and Distinguished Engineers often blend multiple archetypes, balancing technical depth with organisational influence.

---

When Does Your Business Need a Staff Engineer?

Not every company needs a Staff Engineer immediately, but as teams scale, having strong technical leadership without forcing top engineers into management becomes crucial.

You likely need a Staff Engineer if:
✔️ Your engineers lack a clear technical leader but don’t need another manager.
✔️ Large technical decisions are made inconsistently or without long-term vision.
✔️ High-impact technical challenges are falling through the cracks.
✔️ Your engineering team is scaling quickly, and architecture isn’t keeping up.

---

How to Become a Better Staff Engineer

If you’re already a Staff Engineer (or aspiring to be one), focus on these core skills:

• Influence Without Authority – You won’t always have direct reports, so you must earn trust and drive alignment through strong technical reasoning.
• Clear Communication – Great Staff Engineers make complex ideas understandable for both engineers and non-technical stakeholders.
• Technical Depth & Breadth – Balance deep expertise in specific areas with the ability to connect dots across systems.
• Mentorship & Knowledge Sharing – A great Staff Engineer elevates the entire team, not just their own work.

---

Final Thoughts

A great Staff Engineer isn’t just a senior developer who codes more. They are technical leaders who shape engineering excellence, bridge business and technology, and help teams execute at their best.

Whether you’re an engineer looking to grow into this role or a business deciding if you need one, understanding these archetypes can help ensure the right fit and maximise impact.

Understanding Component Architecture Design in Modern Web Development

 

When building modern web applications, we need a system that allows for scalability, maintainability, and reusability. This is where component architecture design comes in. Popular frontend libraries like React and Vue are built around this concept, enabling developers to break their UI into self-contained, reusable components.

In this post, we'll explore what component architecture is, why it's beneficial, and how to design a structured component-based project using React (or Next.js). To make it practical, let's consider a simple to-do list application.

---

What Is Component Architecture?

Component architecture is a way of designing an application where the UI is divided into smaller, independent pieces called components. Each component is responsible for rendering a piece of the interface and can manage its own state and behavior.

For example, in a to-do list application, different parts of the UI can be separated into components such as:

• TodoItem (displays an individual to-do task)
• TodoList (lists all tasks)
• AddTodoForm (allows users to add new tasks)
• FilterControls (lets users filter completed and pending tasks)

Each of these components can be developed, tested, and reused independently.

---

Benefits of Component-Based Design

1. Reusability

Instead of duplicating code, we can reuse components throughout the application. For instance, a Button component can be used for adding, deleting, or marking tasks as complete with minor styling adjustments.

2. Maintainability

Since components are modular, updating or fixing bugs in one area of the application doesn't impact other parts, making maintenance easier.

3. Scalability

As the application grows, new features can be added by simply creating new components or enhancing existing ones.

4. Separation of Concerns

Each component has a clear responsibility. The TodoItem component only renders a task, while the AddTodoForm component handles user input.

---

Structuring a To-Do Application with Components

Let's break down a simple component structure for our project:

/components
   ├── TodoItem.js
   ├── TodoList.js
   ├── AddTodoForm.js
   ├── FilterControls.js
   ├── Layout.js
/pages
   ├── index.js  (Main application page)

In Next.js, which is a React framework, the /pages directory determines routing, while the /components directory houses reusable UI components.

---

Implementing Key Components

TodoItem Component (Displaying a Task)

import React from 'react';

const TodoItem = ({ task, onToggle }) => {
  return (
    <div className="border p-2 rounded flex justify-between">
      <span className={task.completed ? "line-through" : ""}>{task.text}</span>
      <button onClick={() => onToggle(task.id)}>
        {task.completed ? "Undo" : "Complete"}
      </button>
    </div>
  );
};

export default TodoItem;

TodoList Component (List of Tasks)

import React from 'react';
import TodoItem from './TodoItem';

const TodoList = ({ tasks, onToggle }) => {
  return (
    <div className="space-y-2">
      {tasks.map((task) => (
        <TodoItem key={task.id} task={task} onToggle={onToggle} />
      ))}
    </div>
  );
};

export default TodoList;

AddTodoForm Component (Adding New Tasks)

import React, { useState } from 'react';

const AddTodoForm = ({ onAdd }) => {
  const [text, setText] = useState("");

  const handleSubmit = (e) => {
    e.preventDefault();
    if (text.trim()) {
      onAdd(text);
      setText("");
    }
  };

  return (
    <form onSubmit={handleSubmit} className="flex space-x-2">
      <input 
        type="text" 
        value={text} 
        onChange={(e) => setText(e.target.value)}
        placeholder="Add a new task"
        className="border p-2 rounded"
      />
      <button type="submit" className="bg-blue-500 text-white px-4 py-2 rounded">
        Add
      </button>
    </form>
  );
};

export default AddTodoForm;

---

Composition: Bringing It All Together

In Next.js, we can create a homepage that puts these components together:

import { useState } from 'react';
import TodoList from '@/components/TodoList';
import AddTodoForm from '@/components/AddTodoForm';

export default function HomePage() {
  const [tasks, setTasks] = useState([]);

  const addTask = (text) => {
    setTasks([...tasks, { id: Date.now(), text, completed: false }]);
  };

  const toggleTask = (id) => {
    setTasks(tasks.map(task => task.id === id ? { ...task, completed: !task.completed } : task));
  };

  return (
    <div className="container mx-auto p-4">
      <AddTodoForm onAdd={addTask} />
      <TodoList tasks={tasks} onToggle={toggleTask} />
    </div>
  );
}

---

Best Practices for Component Architecture

1. Keep Components Small & Focused – Each component should have a single responsibility.
2. Use Props for Data Flow – Components should receive data via props instead of depending on global state.
3. Extract Reusable Logic – Use hooks like useTodoData() for shared logic.
4. Organize Files Logically – Follow a structure that makes navigation easy.
5. Optimise Performance – Use React.memo and lazy loading for better efficiency.

---

Conclusion

Component architecture is a game-changer in modern frontend development, making applications more maintainable, scalable, and efficient. By designing applications with a well-thought-out component structure, we can build rich, interactive user experiences without sacrificing code quality.

Whether you're building a to-do list app, a social media platform, or a complex dashboard, breaking it down into reusable components is the key to success. Happy coding!

Monorepos in Frontend Development: When, Why, and How to Use Them

 

Monorepos are gaining traction in frontend development, with teams looking for better ways to manage shared code, dependencies, and collaboration across multiple projects. But as with any architectural choice, they come with trade-offs.

Are monorepos the right choice for your team? Let’s break it down.

---

What is a Monorepo?

A monorepo (short for "monolithic repository") is a single code repository that contains multiple projects—such as frontend apps, backend services, shared UI components, and utilities. Instead of managing separate repositories, everything lives in one place, often with tools to handle dependencies and build processes efficiently.

Monorepo vs. Polyrepo

---

Why Use a Monorepo?

✅ 1. Shared UI Components and Logic

Frontend teams often maintain design systems, component libraries, and utility functions used across multiple projects. With a monorepo, these shared resources are versioned and updated in sync, reducing duplication and inconsistencies.

Example:

• /apps/web-app/ – The main React app
• /apps/admin-dashboard/ – A separate admin interface
• /packages/ui-library/ – Shared React components
• /packages/utils/ – Reusable helper functions

Instead of publishing @my-org/ui-library to an internal registry, teams consume the latest changes directly inside the monorepo.

---

✅ 2. Simplified Dependency Management

A monorepo centralizes dependency management, preventing “dependency drift” where different projects run conflicting versions of the same package. Tools like PNPM Workspaces, Turborepo, or Nx help enforce consistent package versions across all projects.

---

✅ 3. Atomic Changes and Cross-Project Refactoring

Making changes across multiple projects is easier in a monorepo. Instead of opening pull requests across different repositories, you update everything in a single commit, ensuring that related changes stay in sync.

Example:

• Polyrepo: Update Button in ui-library, publish a new version, then update web-app and admin-dashboard separately.
• Monorepo: Update Button in /packages/ui-library, and all consuming apps get the changes immediately.

---

✅ 4. Faster CI/CD with Incremental Builds

Monorepos avoid unnecessary rebuilds by using caching and dependency graphs. If only web-app is modified, tools like Turborepo or Nx ensure that only web-app is rebuilt—saving time in CI/CD pipelines.

---

Challenges and Trade-Offs of Monorepos

🚧 Tooling Complexity – Requires setup with PNPM Workspaces, Nx, Turborepo, or Lerna to handle dependencies, versioning, and caching.

🚧 Access Control Issues – In large organizations, fine-grained access control can be trickier than with separate repositories.

🚧 Scaling Issues in Massive Codebases – At a certain scale, even monorepos need additional optimizations (e.g., Facebook uses Buck, Google uses Bazel).

🚧 Learning Curve for Teams – Not all developers are familiar with monorepo tools, which can slow down onboarding.

---

Best Practices for Using a Monorepo in Frontend Development

1️⃣ Choose the Right Tooling – For JavaScript/TypeScript projects, consider PNPM Workspaces (lightweight), Nx (scalable), or Turborepo (fast builds).

2️⃣ Enforce Code Ownership and Boundaries – Use ESLint rules, Code Owners, and package constraints to prevent accidental dependencies between unrelated projects.

3️⃣ Optimize CI/CD with Incremental Builds – Avoid rebuilding everything by using task runners that detect what actually changed.

4️⃣ Use Independent or Fixed Versioning – Decide if shared packages should have a single version (simpler) or independent versions (more flexibility, but more maintenance).

5️⃣ Keep Documentation Up-to-Date – Monorepos introduce new workflows; good documentation ensures teams stay productive.

---

When Should You Use a Monorepo?

✅ You have multiple frontend apps (e.g., marketing site, dashboard, admin panel) sharing UI components and logic.
✅ You want a single source of truth for dependencies and shared libraries.
✅ Your team frequently makes cross-project changes.
✅ You want to optimize CI/CD with incremental builds and caching.

When to stick with polyrepos?
❌ If projects are completely independent with no shared code.
❌ If teams require strict access control between projects.
❌ If existing workflows heavily depend on separate repositories and versioning.

---

Final Thoughts

Monorepos aren’t a silver bullet, but for teams managing multiple frontend apps with shared dependencies, they provide better collaboration, faster builds, and easier cross-project refactoring.

The key is using the right tools and enforcing structure to keep complexity manageable.

Is your team using a monorepo, or considering the switch? What’s been your biggest challenge or success? Let’s discuss!

Building for the Long Game: Avoiding Accidental Complexity in Frontend Development

Modern frontend development is powerful—but with power comes complexity. Are we overcomplicating things in the name of "best practices"?

Every year, new frameworks, state management tools, and architectures promise better performance, cleaner code, or easier scalability. But often, the biggest challenge isn’t the technology itself—it’s the accidental complexity we introduce while trying to optimize too soon.

Where Accidental Complexity Creeps In

🚩 Over-Abstraction in Component Design – A simple button component doesn’t need five layers of abstraction. Sometimes, duplication is better than premature generalization.

🚩 Over-Engineering State Management – Not every app needs Redux, Recoil, or XState. If your global state solution is harder to understand than the problem it solves, it’s probably the wrong tool.

🚩 Microservices and Monorepos When a Simple Repo Works – Splitting everything into isolated services or packages can add overhead. If a team spends more time managing dependencies than shipping features, is it really a win?

🚩 Blindly Following Trends – Just because React Server Components, Edge Functions, or GraphQL are hot topics doesn’t mean they fit your use case. Choose tech based on real needs, not hype.

How to Keep It Simple and Scalable

✅ Start Small, Scale When Needed – A useState might be all you need. A single repo might outperform a monorepo for your team. Scale complexity only when bottlenecks appear.

✅ Prefer Readability Over Cleverness – Code should be written for humans, not just for the compiler. If a junior dev can’t onboard quickly, the abstraction is likely too complex.

✅ Optimize for Developer Experience (DX) Too – Faster builds, fewer dependencies, and clear API boundaries improve developer happiness, which translates to better product velocity.

The Best Frontend Codebases Aren’t the Most Complex—They’re the Most Understandable

Technology evolves. Simplicity scales.
What’s the most unnecessary complexity you’ve had to untangle in a frontend project? Let’s discuss.

Web Development Trends in 2024: What Developers Need to Know

As a principal engineer who has observed the evolution of web technologies over the years, I remain both excited and cautious about the latest trends shaping our field. In 2024, technologies like AI, serverless architectures, and modern frameworks are at the forefront, guiding how we create efficient, secure, and user-centric web experiences.

AI: More Than Just Chatbots

Artificial Intelligence has evolved far beyond simple chat automation. Today, AI algorithms drive personalised user experiences, tailoring content and interface adjustments to individual preferences. Automated QA tools leverage AI for early bug detection, while predictive analytics optimise performance and anticipate user needs. Incorporating AI into our development workflows is no longer a luxury but a requirement for staying competitive.

Serverless Computing

Serverless computing continues to be a major disruptor. Platforms such as AWS Lambda and Azure Functions let developers focus purely on code, without dealing with infrastructure. This approach not only reduces costs but also scales seamlessly based on demand, simplifying deployments. However, developers need to address concerns like latency and cold-start times to ensure optimal performance.

Low-Code and No-Code Platforms

There was a time when writing custom HTML and CSS from scratch was a mark of pride. Now, low-code and no-code tools are transforming development by enabling rapid prototyping and even empowering non-developers to create functional websites. While traditional coding remains vital, these platforms are invaluable for speeding up development, particularly for MVPs and in-house applications.

Jamstack and WebAssembly

Jamstack architecture is fundamentally reshaping web development by decoupling the frontend from the backend, which results in faster and more secure web applications. Static site generation combined with APIs for dynamic content provides lightning-quick performance. WebAssembly (Wasm) is another game-changer, enabling near-native execution of languages like C++ and Rust directly in the browser, making complex web apps feasible and performant.

Conclusion

The web development landscape in 2024 is all about striking a balance between embracing innovation and maintaining efficiency. Developers must leverage new technologies thoughtfully to deliver exceptional user experiences while keeping an eye on the fundamentals of clean, scalable code. Stay flexible, keep upskilling, and remember: good development practice never goes out of style.

Deno 2.0 - Mono-repos and workspaces

 This article will cover configuring a mono-repo, workspaces, vite and a library package all in Deno 2.0

Project structure:

`deno task dev` will spin up a sample vite website, where we can see the library being consumed.

We'll do this in a few steps.  First we'll create the base Deno mono-repo, then we'll create the simple-login library. And lastly a vite website and hook it all together.

Firstly, ensure you have Deno runtime installed on your machine.  I'll do a separate article on configuring this within Docker containers.

Check: https://docs.deno.com/runtime/

Then

• Create a new folder called `deno-monorepo`
• Create a file called `deno.json` inside it.
• Add the following contents into it:

{

  "workspace": ["./simple-login", "./website"],

  "imports": {

    "@std/path": "jsr:@std/path@^1.0.7"

  },

  "tasks": {

    "dev": "deno run -A npm:vite website"

  }

}

Don’t Look Back in Anger: Mastering the Art of High-Demand Ticketing Events

 In today's fast-paced digital landscape, ensuring the seamless operation of online services during high-demand events is paramount. The complexity of managing platforms like Ticketmaster, especially during major ticket releases, like Oasis 2025, cannot be overstated. The stakes are high, not just in terms of revenue but also in maintaining customer trust and brand reputation.

Anticipation and Preparation

The journey begins long before the event date is announced. It starts with careful planning, anticipating potential challenges, and preparing for all possible scenarios. This involves understanding the scope of the event, the expected traffic, and the unique demands it might place on our systems.

Capacity planning is a critical component of this phase. Estimating the expected load is both an art and a science, requiring historical data analysis, understanding current market trends, and considering external factors that could drive traffic spikes. Once we have a reasonable estimate, the next step is ensuring that our infrastructure can handle this load with room to spare. This often means scaling up servers, optimizing databases, and ensuring our content delivery networks (CDNs) are primed to handle the increased demand.

Equally important is load testing. Simulating the event conditions allows us to identify potential bottlenecks and address them proactively. This might involve fine-tuning our systems, updating software, or even making more significant architectural changes to ensure we can handle the anticipated demand without compromising on performance.

Maintenance and Monitoring

As the event approaches, the focus shifts to maintenance and real-time monitoring. This phase is about ensuring that everything is in place and functioning as expected. It’s not just about keeping the servers running but about ensuring optimal performance and quick response times.

Real-time monitoring tools are crucial in this phase. They provide visibility into every aspect of the system, from server load and database performance to network latency and user experience. This visibility allows us to identify issues as they arise and address them before they escalate. Additionally, having a robust incident response plan is essential. This plan outlines the steps to take in the event of an issue, ensuring that everyone knows their role and that issues are resolved as quickly as possible.

Another key aspect is communication. Keeping all stakeholders informed, from the technical teams to customer support and even the end-users, ensures that everyone is aligned and that there are no surprises. Transparent communication also helps in managing customer expectations, especially if there are delays or issues during the event.

Post-Event Reflection

Once the event is over, the work doesn’t stop. The post-event phase is about reflection, learning, and continuous improvement. It’s important to conduct a thorough postmortem analysis to understand what went well and what didn’t. This analysis should be comprehensive, covering everything from the technical performance to the team’s response and communication.

The goal of this reflection is not to assign blame but to identify areas for improvement. Whether it’s fine-tuning the load-testing process, enhancing monitoring tools, or improving incident response times, the insights gained from the postmortem analysis are invaluable in ensuring better performance in future events.

Conclusion

Managing an online ticketing platform like Ticketmaster during high-demand events is a complex and challenging task. It requires meticulous planning, real-time monitoring, and a commitment to continuous improvement. By focusing on these areas, we can ensure that our platforms not only meet but exceed expectations, providing a seamless and reliable experience for our customers. The ultimate goal is to maintain trust and deliver a service that stands out, even in the face of immense demand.
