Stuff I’ve Shipped Under Pressure
Every hackathon I have shipped at, in order: what got built, where, and how it placed.
MLH Midnight Hackathon
Online
Won the Gaming Track. Built Among-Midnight, an Among Us clone with a zero-knowledge anti-cheat layer. The role deal, every kill, every vote and every ejection is bound to an on-chain commitment, so a rigged dealer or a stuffed vote stops being against the rules and starts being cryptographically impossible.
DEV Challenge
Online
Won two editions back to back. May went to a deep-dive write-up on Gemma, July to Best Use of Snowflake. Judged publicly against an open field, for over $300 in prizes.
Hacktropica
Asansol, West Bengal
Won Best Use of Presage SDK. Built SoloFit, a fitness app that reads physiological state (blood pressure, resting heart rate, HRV) from a camera scan, then has Gemini write that day's training and diet from the reading. Generic apps hand you the same session whether you slept eight hours or three; this one measures instead of assuming.
Frosthacks S02
Adisaptagram, West Bengal
Top 2 in the Safety Track. Developed a Web3 anonymous reporting system for workers, with SMS offline support and IPFS evidence storage to avoid data distortion.

Kalyani, West Bengal
Finalist. Built an AI/ML AWS deployer orchestrator using an Oumi fine-tuned API model to act as an automated SRE agent.
Xibit Hackathon
Barasat, West Bengal
Won 2nd place in an 8-hour build sprint with a Wellness Nudge app that reduces stress and reminds users to exercise.

East India Blockchain Summit 2.0
