Hi, I’m Abhay Chauhan.
I craft high-performance web applications, developer tooling, and modern digital experiences with React 19, Next.js 15, and TypeScript.
Background & Engineering Philosophy
I am an independent software engineer based in Delhi, India, with a relentless focus on clean architecture, web performance, and user ergonomics. For me, every line of code is a promise of quality that end-users directly experience through fluid frame rates, instant interactions, and resilient reliability.
My journey combines deep frontend engineering with solid backend and systems design. I have developed production applications ranging from interactive developer extensions and crypto trading platform prototypes to high-scale business accounting suites and immigration consultancies.
I believe developer experience and user experience are deeply connected. When software is easy to reason about, inspect, and test, teams ship better products faster. That conviction led directly to the creation of Borderly, my popular Manifest V3 Chrome Extension designed to debug and measure DOM layouts in real time.
Core Competencies & Stack
Frontend Architecture
Next.js 15 (App Router, Server Actions, Dynamic Metadata), React 19, React Server Components, TypeScript, Tailwind CSS, GSAP, and Framer Motion.
Developer Tools & Extensions
Chrome Extension Manifest V3, DOM Mutation Observers, client-side developer tooling, Web MCP (Model Context Protocol), and Rollup/Vite bundling.
Backend & Databases
Node.js, Express, PostgreSQL, Drizzle ORM, Prisma, tRPC, REST/GraphQL APIs, and Auth.js / NextAuth for secure credential and session management.
Performance & GEO Optimization
Core Web Vitals remediation (LCP < 2.5s, CLS < 0.1, INP < 200ms), Edge caching, JSON-LD Structured Data, dynamic sitemaps, and Generative Engine Optimization.
Borderly Chrome Extension
Borderly is a zero-tracking, client-side Manifest V3 Chrome Extension that accelerates DOM layout debugging by up to 55%. It empowers frontend engineers, QA testers, and UI/UX designers to instantly outline elements, measure pixel-perfect spacing, and inspect CSS bounding boxes with a single click or keyboard shortcut (Alt+B).
