Full Stack Developer
About
Full Stack Developer with 3 years building production-grade web and mobile applications across MERN, Next.js, and Flutter. I've delivered enterprise systems in HRMS, healthcare, manufacturing, and AI platforms.
Founding Full Stack Developer at UpTye, Kolkata. Helped build the company from the ground up, from hiring the right technical talent to planning projects and developing the platform that 2,000+ employees at a furnace manufacturing company now use daily. Integrated LLM-powered AI features into client platforms. Done microservices and monoliths, picked what fit.
I use AI-assisted tools like Claude, Cursor, GitHub Copilot to ship faster. Not because AI writes my code, but because it helps me think through problems better and deliver cleaner code.
The point isn't clever code. It's systems that scale, that users actually rely on, that make a business run smoother.
