What I'm looking for

I’m looking for a team where I can build secure MERN full-stack products and real-time experiences, optimize UI performance in React/React Native, and ship reliable APIs deployed on AWS.

I’m a Full-Stack Developer specializing in the MERN stack, focused on building real-time web and mobile applications that feel fast and reliable. I design secure REST APIs, optimize React/React Native UIs, and deploy applications on AWS.

At 99Astro, I engineered a custom Chat UI system from scratch—covering message bubbles, timestamps, read receipts, typing indicators, smooth auto-scroll, and rendering optimizations for large-scale conversations. I also improved app performance using React Native Reanimated, memoization, and FlatList virtualization for smooth navigation across screens.

I build dependable backends that sync cleanly with the UI. I implemented API data synchronization with PostgreSQL using optimized queries, pagination, and robust error handling, and integrated the Razorpay payment gateway for wallet recharge with idempotent processing to safely handle retries and duplicate payments.

Earlier, at HMEL, I developed a full-stack employee management system with role-based access control, dashboards, and audit logs to strengthen data security and visibility. I implemented JWT-based authentication and built REST APIs with Node.js/Express, integrating them with React components for seamless data flow.
