Refactoring: rename class/method/variable

-
This refactoring is such a simple idea and you'll find yourself continually doing this as you work and build extra functionality into your web applications. There is also continual need to do this whole debugging and/or refactoring existing code.

Take for example the below class:

class person {
  public $w;
  function clchrlypr() {
    // calculate hourly pay rate of employee
    ...
    return $var;
  }
}

Now let's look at the below example:

class employee {
  private $wage;
  public function calculateHourlyPayRate() {
    // do some magic
  }
}

Which was easier to read and follow?  I would hope the second snippet was clearer, however the first is an all to common sight in some projects and seeing this code makes you really have to think hard, and quite frankly wastes time  if we had written the second block of code in. The first place things would have been so much easier for our colleague.

The Concept of True North in Lean Methodology: A Toyota Perspective

-
The Concept of True North in Lean Methodology In the world of Lean methodology, one of the most fundamental and guiding principles is the concept of "True North." This concept, often associated with Toyota, is at the core of Lean thinking and serves as a compass for organizations on their continuous improvement journey. In this blog post, we will delve into the significance of True North, its origins, and how it plays a pivotal role in the Art of Lean. Origins of True North To understand the concept of True North, we must first look back at the origins of Lean thinking and its close association with Toyota. The principles of Lean, as they are known today, were largely developed and perfected within Toyota's manufacturing operations. Taiichi Ohno, the father of the Toyota Production System (TPS), played a central role in crafting these principles. He emphasized the need for a clear direction that would guide every action and decision within the organizati...

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 efficient...

Serverless Architectures: Simplifying Backend Development for Scalable Apps in 2025

-
Serverless architectures have redefined backend development, offering scalability and cost-efficiency without the overhead of managing servers. As someone who has led Laravel and Node.js projects, I have seen serverless solutions like AWS Lambda and Netlify Functions streamline workflows and handle unpredictable traffic spikes. This article delves into serverless trends for 2025 and provides actionable insights for developers. Understanding Serverless Architectures Serverless computing allows developers to execute code in response to events without provisioning servers. Cloud providers like AWS, Google Cloud, and Azure manage infrastructure, automatically scaling resources based on demand. This model reduces costs, as you only pay for compute time used. In 2025, serverless adoption is surging, with Gartner predicting 75% of enterprise data will be processed at the edge by 2026, complementing serverless paradigms. Benefits for Modern Web Apps Scalability : Serverless functions scal...
