Sambit Maity — Full-Stack Software Engineer

Kolkata, India · official.sambitmaity@gmail.com · Immediate joiner, open to full-stack & backend engineering roles: on-site, hybrid or remote

Laravel & Node.js engineer who owns products end to end — from architecture and APIs to servers, automation and the pixels on screen.

About

I don't hand off at the API boundary. I design the architecture, write the backend, build the interface, provision the servers, wire the automations and stay on call for what I ship. Three years across four teams taught me that the best engineering is the kind nobody has to think about — fast, reliable, and quietly doing its job.
