About

I’m a Senior Frontend Engineer who builds fast, scalable web and mobile experiences for fintech and e-commerce platforms serving millions of users.

Over the past 3+ years, I’ve specialized in React.js, Next.js, TypeScript, and React Native—turning complex business requirements into intuitive interfaces that users love and systems that scale.

What I’ve built:

  1. A custom 3D product visualization SDK for Flipkart’s 500M+ user mobile app using Three.js and React Native
  2. Real-time transaction dashboards managing $150M+ in annual cross-border payments at moneyHOP
  3. Five production applications from scratch—mobile apps, web portals, and internal tools serving 10,000+ monthly users
  4. Performance optimizations that reduced load times from 4.2s to 1.8s while maintaining feature-rich experiences

My technical toolkit:
Frontend: React.js, Next.js, TypeScript, React Native, Tailwind CSS, ShadCN UI
State Management: Redux Toolkit, Zustand, TanStack Query
Full-Stack: Node.js, Express.js, MongoDB (MERN)

What sets me apart:
I don’t just write code—I solve business problems. Whether it’s building AI-powered product discovery interfaces, implementing secure payment flows, or architecting reusable component libraries, I focus on shipping solutions that drive real value.
I thrive in fast-paced environments, collaborate seamlessly with cross-functional teams, and have a track record of delivering high-impact features in Agile settings at companies like Flipkart and moneyHOP.

Currently: Open to SDE-2 opportunities where I can build innovative user experiences at scale.
Let’s connect if you’re building something exciting in fintech, e-commerce, or consumer tech.

CodeVitals — Codebase Governance CLI & AI Agent Skill for Any Codebase

CodeVitals — Codebase Governance CLI & AI Agent Skill for Any Codebase Ship a lighter, faster website — and keep it that way as your codebase grows. CodeVitals is a zero-dependency CLI and a machine-readable skill for AI coding agents. The measurement core is language-neutral; JavaScript and TypeScript get the deepest support, because bundle weight is where code size turns directly into user-visible slowness. It measures how heavy your code and your shipped JavaScript bundle are, tells you in plain language what that costs your users, and gets stricter automatically as your project scales.

  • Back-End Developer

I Delivered a production-ready web application with a focus on creating a scalable and easy-to-use frontend. I took responsibility for turning product requirements into UI components. I built interfaces, connected REST APIs, managed application state and handled data flows. I worked alongside backend and QA teams to make sure everything functioned reliably from start to finish.

I helped shape the frontend architecture using React, Next.js and TypeScript. I paid attention to writing clean maintainable code, improving performance building reusable components and ensuring consistent experiences for users. I also collaborated with the team, on debugging issues running tests integrating APIs and releasing updates to production.
