The Frontend Developer Is Dead (And That’s Good)

In 2026, “frontend developer” doesn’t mean what it used to.And that’s a good thing.Over the past few years, AI has moved from novelty to daily workflow. It scaffolds components, writes tests, refactors functions, and explains unfamiliar codebases in seconds. What used to take hours now takes minutes.If your definition of frontend engineering is “write components from a design file,” then yes — AI is coming for that role.But the job isn’t disappearing.It’s evolving.And the engineers who understan

Filling the Unit System: IntegrationUnit, AdapterUnit, and the Full Boot Sequence

Last post, the Unit System had its first real types — RuntimeUnit, PackageManager, and defineRuntime(). The runtime layer was done. But a runtime by itself does nothing. It knows how to run things, but nothing is asking it to run anything yet. The system needed the other two unit kinds — integrations and adapters — before any of it would actually connect. IntegrationUnitIntegrationUnit is the interface for framework-specific plugins — React, NestJS, Angular, Docker as an orchestrator, and a

Cursor-Reactive Gradients: Making CSS Respond to Mouse Position

Cursor-Reactive Gradients: Making CSS Respond to Mouse PositionThe logo on my portfolio site changes colour as you move your mouse. Not with a library. Not with a pre-built animation. With about 15 lines of maths that convert cursor position into RGB values and generate a three-point radial gradient in real time.And when you scroll, the same gradient system responds using sine and cosine wave functions.Here's how the whole thing works. The core function: gradientCreatorThe entire grad

I Built a Mini Games Platform With Pure JavaScript (No Framework) And Firebase

I challenged myself to build a browser-based mini games platform without using any heavy frameworks.The goal was simple:Instant playNo downloadsClean architecture100/100 Lighthouse performanceHere’s what I learned building it from scratch.Instead of relying on React or Vue, I structured the platform using modular vanilla JavaScript.Each game is dynamically loaded, keeping the main bundle lightweight and fast.Performance was a top priority.By minimizing render-blocking resources and keeping the D

I Built a JavaScript Interview Prep Platform with Interactive Code Visualizations

If you've ever bombed a JavaScript interview because you understood a concept but couldn't explain it clearly — this post is for you.I've been building jsinterview.dev — a free JavaScript interview prep platform that teaches you concepts through interactive step-by-step code visualizations. Think of it as Python Tutor, but purpose-built for JS interviews. The Problem I Was SolvingMost JS learning resources fall into one of two camps:Read-heavy docs — great for reference, terrible for buildi

Exploring Next.js advanced routing and beyond

Routing is the backbone of any modern web application. Get it right, and users navigate fluidly through your content. Get it wrong, and you're fighting sluggish transitions, tangled layouts, and brittle URL structures. Next.js offers one of the most flexible routing systems in the React ecosystem — but taking full advantage of it requires understanding the patterns that go beyond a basic pages/index.js.This article covers the techniques that matter most: dynamic routing, nested layouts, advanced

Next.js Module Graphs: The Hidden Architecture Behind Server and Client Components

Most Next.js tutorials tell you: "Server Components run on the server, Client Components run on the client." That's true, but it hides a massive architectural detail that will confuse you the moment you try to share state between them.In this article, we'll build a small experiment, observe something that seems impossible, and then peel back the layers of the Next.js rendering pipeline to understand exactly what's happening. The ExperimentLet's create a simple closure-based state module and

Offline-first React without the boilerplate — how I built connectivity-js

Picture this: your user is on a train, editing a doc. Their signal drops. They save. Nothing happens. They reload. Their changes are gone.This happens because most web apps are secretly online-only — they just pretend otherwise.After one too many production incidents where a user lost data, I decided to fix this properly and built connectivity-js — a declarative, type-safe, offline-first connectivity layer for JavaScript and React. The problem with ad-hoc connectivity handlingThe typical pa

Week 20 React Recap — Context API, useReducer, Authentication & Real Project Practice

This week was mainly focused on deepening my understanding of Context API and useReducer, but this time not just through theory or small examples — I implemented these concepts inside real projects.Most of my learning this week happened inside my WorldWise project, where I practiced advanced state management and application architecture.Instead of just watching tutorials, I tried to apply every concept directly into a real codebase.That made a huge difference. Practicing Context API in a Re

How We Engineered a 73% Cache Hit Rate Travel App with Vite + React

GoNepal - Cache-First Travel for Nepal’s Toughest NetworksGoNepal started out as a hackathon project, but right from the beginning, we focused on one big problem: Nepal’s network can be flaky, especially in the mountains, and most travel apps just aren’t built for that. So we built GoNepal to keep working even when your signal drops, your battery’s low, or you’re stuck translating between three languages.The Core Idea: Cache Comes FirstMost apps treat caching like an afterthought. We flipped tha
