Summary

Rockstar🎓
Top SchoolPeter Lai is a blockchain-focused software engineer with 10 years of experience building layer-2 protocols, SDKs, APIs and secure backend systems across languages like PHP, Go and JavaScript. He contributed to widely used open-source projects such as web3.php and has integrated exchange and DEX functionality for CCXT and Tokenlon, blending deep protocol knowledge with practical SDK and subgraph implementations. His work spans smart contracts, DeFi risk mitigation, hot-wallet cost optimizations and custom matching engines, demonstrating both research-driven design and production-grade delivery. Based in the Netherlands, he combines curiosity about edge technologies (MEV, zk proofs, PoS) with hands-on engineering—an example being his BOLT layer‑2 design and a reverse-proxy for the Diode network. Notably, he pairs frontend leadership and CI/CD/monitoring improvements with low-level blockchain tooling, making him effective across the full stack of decentralized systems.
