Joint

Joint is a peer-to-peer exchange protocol for instant crypto-to-crypto swaps and interactive crypto-to-cash trades. As CEO, I led a team of 11 engineers and designers, and the exchange processed over $300,000 in volume. I wrote the Solidity contracts for markets, liquidity, orders, swaps, fees, mediation, staking, and rewards, built the React and TypeScript trading interfaces, and oversaw a NestJS event indexer on PostgreSQL and Redis.
