Actionable walkthroughs on React, Next.js, and TypeScript; cloud-native patterns on Azure/Kubernetes; and career playbooks for leading high-impact engineering teams. Short, practical, and battle-tested from real fintech delivery.
Most developers think tech lead interviews are about proving how good they are technically. They’re not. At tech lead level, competence is assumed — judgment is evaluated. Here’s what hiring managers actually look for, and what separates candidates who almost get promoted from those who consistently do.
Great developers don’t appear by accident — they’re shaped through guidance, trust, and repetition. Mentorship isn’t about giving answers; it’s about upgrading how someone thinks. Here’s how to mentor effectively without micromanaging or burning out.
Many developers believe leadership starts with a title. It doesn’t. Most tech leads are already leading long before the promotion arrives — influencing decisions, unblocking teams, and setting technical direction without formal authority. Here’s how to build that trust.
Most first-time tech leads don’t fail because of bad code — they fail because they never stop thinking like individual contributors. Seven behaviours that separate great tech leads from the ones who quietly struggle, and the three rules of leadership that change everything.
Technical decisions are rarely just technical — they affect delivery speed, team morale, operational risk, and sometimes millions of users. Tech leads don’t make better decisions because they know more. They do it because they think differently. Here’s how.
Becoming a Tech Lead isn’t just the next step after Senior Engineer — it requires a fundamental mindset shift. Seven shifts every senior developer has to make if they want to move from writing great code to leading high-performing engineering teams.
Deploying software is a critical phase in the software development lifecycle. The chosen deployment strategy can impact the stability, performance, and user experience of the application. This blog will explore various deployment strategies, discussing their advantages, disadvantages, and implementation details.
This is a step-by-step guide for creating a component library using TypeScript, Rollup, Jest for testing, styled-components for styling, Storybook for Component Library development, and CircleCI for automation.
Welcome to this comprehensive Firebase Authentication tutorial, where we will guide you through creating a robust email authentication system for your web application. Firebase offers a powerful suite of tools for building seamless authentication experiences, and by the end of this tutorial, you will have a fully functional system in place.
Frontend development has evolved rapidly over the years, and with the growing complexity of web applications, maintaining a high standard of code quality has become more crucial than ever. Continuous Integration (CI) and Continuous Deployment (CD) pipelines play a pivotal role in achieving this by automating the process of testing, linting, and deploying code changes.
Frontend development is a dynamic field that is constantly evolving with new frameworks, libraries, and technologies emerging every year. Whether you are just starting out in web development or looking to update your skills, having a solid roadmap helps provide direction and structure to your learning journey. In this post, we will walk through the key frontend skills and technologies to learn in 2024 to become an effective frontend developer.
As a Senior Web Developer and mentor, I live and breathe websites. So when my own site started slowing to a snails pace, I knew it was time for an extreme makeover. Launching my freelance and web development career seven years back, I hastily threw together a simple WordPress site. It did the job at first, but over time as I added more plugins, images, and features, the site became bloated and slow.
Testing is an essential part of any software project, but tests are often overlooked when it comes to React and Next.js. In this article, I’ll cover the main types of testing that you can do with your React and Next.js codebases so that you can ship high-quality code with confidence.
Welcome! In this post, I will be building a progressive web application (PWA) using React and Next.js. I will explain the concepts of PWAs, service workers, and offline caching. I’ll start by talking about what a PWA is and why you should build one. Then I’ll go through how to install the necessary tools on your machine as well as some basic setup on GitHub. Finally, I’ll walk through creating an app with React and Next.js that uses Google’s Firebase Cloud Functions for authentication purposes!
Performance optimization is important for building amazing applications for the web. When your application loads quickly and runs smoothly, users will be delighted with their experience and return to your site again and again. In this article, I’ll cover tips and techniques to improve the performance of React and Next.js applications. I’ll also discuss how to measure the performance of your application so that you can identify improvements in real-time.
Next.js is a framework for building server-rendered React applications with minimal configuration. It’s designed to be used in conjunction with a standard Express server, as well as other libraries such as Redux or GraphQL. In this guide, we’ll walk through the basics of setting up a Next project from scratch and explore its key features and benefits!
React is the most popular framework for building user interfaces. Today, it’s used by Netflix, Airbnb, and Instagram. As a developer or designer who plans to use React in their next project, you’ll want to know which components are available. This article will help you get up to speed with ten fundamental React components that are widely used in modern web development.
Reducers are special functions that help to manage information in a program called Redux. Think of Redux like a giant toy box with all sorts of toys inside. A reducer is like a special helper who takes out a toy, plays with it, and then puts it back in the toy box.
In Redux, “state” is like a box of toys that we want to change or update. But, we can’t just go into the box and start changing things, we have to follow some rules. Think of it like playing a game where you can only make moves by following certain instructions.
In simple terms, configureStore is a tool that helps you create a “store” in your React app. A store is like a big box that holds all the data for your app.
In Redux, we have something called a store that holds all the data of our application. mapStateToProps and mapDispatchToProps are two functions that allow our React components to interact with this store.
GraphQL is a data query language developed by Facebook. It lets you write queries to get your data from a server, instead of writing multiple REST API calls with different endpoints and parameters. In this tutorial, we will learn how to fetch data using GraphQL in our React application.
You’ve probably heard of React Suspense, but do you know what it is? In this article, I will explain what React Suspense is and how it works. I will also cover common use cases for implementing React Suspense in your app.
React hooks are used to add state to your component. They can be used in both functional components and classes, but they’re especially useful if you want to define state outside of the render method. In this post, we’ll go over two hooks that can help with this: useState and useRef. We’ll also look at how these work inside of a simple form so you can see how they’re different from each other when it comes time to use them in your own projects!
It’s not always clear how to test code that executes asynchronously. Testing asynchronous code can be tricky. If a function is supposed to return data when it’s finished running but doesn’t do so synchronously, you’ll probably want to test that the result is ready and available. That’s where async unit tests come in!

To add navigation to your React application you need to follow a few steps
You've built a kickass React app and it's time to add some data. You could use an API, but what if you don't know how? Or maybe you've built an API with your favorite tool but have no idea how to fetch that data into your application? Don't worry — we're about to walk through the basics of fetching data from an API with React.
ReactJS is a JavaScript library created by Facebook for building user interfaces. It is used for building large applications that can be rendered on both the client and server sides. ReactJS uses a "virtual DOM", which allows it to be more efficient than other libraries. It has features like data binding and modularity, which make it easier to maintain large applications than other libraries.
