Summary
🤩
Rockstar🎓
Top SchoolWilliam Smith is an Apps Lead with 9 years of experience building blockchain, DeFi, and Web3 systems, currently leading app efforts at Subzero Labs from Los Angeles. As a Senior Protocol Engineer on Sui at Mysten Labs, he helped harden a next‑generation smart contract platform by implementing a two‑phase commit protocol, improving write‑ahead logging, and parallelizing checkpointed transaction execution for crash recovery and high throughput. He pairs product-facing app leadership with deep core infrastructure chops honed at Meta (containers and ML recommendation systems) and startups like royal.io, and brings uncommon systems discipline from prior satellite payload engineering and years as a US Marine avionics technician. A UC Berkeley EECS graduate, he’s motivated by building toward a trustless, equitable decentralized future and is comfortable bridging low‑level distributed systems work with shipping real user-facing products.
