Previously senior lead engineer at Funding the Commons (Commons Labs), working on public-goods funding infrastructure; before that co-founded NexusFi, a liquid staking protocol on Nibiru. Eight products shipped with DecenLabs across DeFi, tooling and protocol infrastructure. ## What I work on Privacy and infrastructure, and systems that have to be right: ledgers that can't lose money, payment rails, zero-knowledge identity, and tooling that lets AI agents act safely with money and permissions. Most of my recent work is in Go and TypeScript; I've shipped smart contracts on Ethereum, Base, Polygon, BNB Chain, Solana, Aptos, Sui, Mina, Starknet, Stellar, Filecoin, Nibiru and Canton. ## Projects ### [Aequitas Ledger](https://shikhar.xyz/projects/aequitas-ledger) A ledger that can't lose a cent, settling 268k transfers a second on a single machine.
