I'm a systems engineer. I build decentralized systems and the tooling that makes them usable. Most of my work lives somewhere between cryptography, distributed systems, and developer experience.

Some highlights: won ETHIndia 2024 with zkRail, coauthored ERC-7518 for globally compliant RWA tokenization, built the first ERC-4337 multichain wallet, and developed core infrastructure for EIP-7702 and EIP-2771 meta-transaction relayers.
