About

I'm an Electronics & Communication Engineering undergraduate at Cooch Behar Government Engineering College (2023–2027), currently interning as a Frontend Developer & QA Engineer at SRS Next Solve LLP (brainlea.com).

I build fast, resilient web applications — specializing in TypeScript, React.js, Next.js, and RESTful architectures. I focus on sub-second render performance, modular component design, and zero-trust security.

When I'm not writing code for production, I maintain open-source software like biraj-mpv-conf, practice DSA on LeetCode, and build tools that solve practical engineering challenges.
