About

I build things
that shouldn't
exist yet.

Second-year B.Tech CSE at IEM, University of Engineering & Management, Kolkata. I live at the intersection of zero-knowledge cryptography, blockchain, and production-grade full-stack engineering.

My flagship project CRCS uses Groth16 zk-SNARKs and threshold secret sharing to build collusion-resistant credential systems — it won Joint First Prize at ISEA Hackathon 2026 at ISI Kolkata and is being incubated for MeitY's Blockchain India Challenge.

I also build on Stellar/Soroban, contribute to open source, hunt CTF challenges, and learn web app penetration testing in my spare time. Currently Treasurer at IEM Toastmasters & Google Women Techmakers member.
