Building realtime systems for AI & Web3

I'm a Full Stack developer based in Bengaluru with 6 years of experience turning complex problems into products people actually enjoy using.

Currently building a terminal-style prediction market intelligence platform focused on semantic search, realtime market streams, and cross-chain trading infrastructure.

Interested in building systems that combine realtime infrastructure, intelligent search, and human-centric interfaces — especially across AI, prediction markets, and decentralized finance.
