about
I’m a software engineer at FilOz Inc., where I build open-source systems for Filecoin. My work spans backend services, on-chain indexing, contract-integrated interfaces, observability, CI/CD, and production releases.
I work across the full lifecycle: understanding a protocol, designing its data flow, shipping a useful interface, and keeping the system reliable in production. Before FilOz, I worked at Blockflow on Web3 explorers, subgraphs, and JavaScript tooling.
I earned a B.Tech in Mechanical Engineering from IIT Roorkee in 2025.
