Full Stack Engineer \| React Native \| Next\.js \| Node\.js \| GraphQL

## About

I build full\-stack systems that run at scale — from the database schema to the pixel on screen\. In 3\+ years I've architected admin platforms, real\-time commerce apps, and distributed backends now handling 10,000\+ transactions a week\. At Buncha Technologies, I owned end\-to\-end product development: designing systems, shipping mobile apps to production, and building the internal tooling that kept operations running\. I didn't just write code — I made decisions that moved metrics\. Impact I'm proud of: → Architected a unified Admin Portal \(Next\.js, GraphQL, Node\.js microservices\) — boosted operational efficiency 40% → Took the shopper app from concept to store rollout — React Native, Node\.js, Firebase, WebSocket\-driven live order tracking → Cut release friction 70% by building CodePush OTA pipelines → Standardised reusable component libraries, cutting feature delivery time 25% Outside of work I build my own products\. Shadow Toolkit is a 100%\-in\-browser developer platform — 175 tools, zero server uploads, built on WebAssembly and Canvas 2D\. Instasave is a distributed video pipeline handling chunked recording, signed cloud uploads, and async BullMQ/FFmpeg processing\. Stack: TypeScript, React, Next\.js, Node\.js, NestJS, GraphQL, PostgreSQL, Redis, BullMQ, Cloudflare Workers, AWS, Docker\. I like owning problems end\-to\-end — from API design to production deployment — and I'm equally comfortable in early\-stage ambiguity or structured teams that value velocity and quality\. Open to Senior / Staff Full Stack roles at product\-led startups or remote\-first teams building something meaningful\. 📩 tanmoy@shadow\.net\.in
