Senior🎓
Top SchoolWilliam Yang is a seasoned developer and technical architect with 13+ years building high-throughput, finance-grade systems across banks, exchanges, and top e‑commerce platforms. He combines deep Java and Python expertise with hands-on experience in MySQL, Oracle PL/SQL, PostgreSQL and large Redis/Codis clusters to deliver robust clearing, settlement and custody infrastructure. Notable work includes leading Bybit’s Off-Exchange Settlement and Proof-of-Reserve implementations, migrating matching engines to in-memory architectures, and operating Shopee promo systems at million-QPS scale. He routinely acts as a half-PM in cross-functional teams, replacing legacy risk logic with auditable, database-native designs and shipping independent tools like a regression testing framework for billion-dollar OTC flows. Comfortable navigating regulatory and product constraints, he brings a bias for precision under pressure and a track record of translating complex financial requirements into pragmatic, production-ready systems. Based in Hong Kong, he now focuses on custody and RWA innovations in the crypto copy-trading space.
