Rockstar🎓
Top SchoolNic Lin is a VP of Engineering based in New Taipei with a decade of experience building high-performance web and blockchain systems. He blends hands-on backend expertise in Ethereum, L2, MEV and censorship-resistance topics with product-facing full-stack work (Rails, React/Vue, Go) and operational leadership at BitoEX. Nic has contributed to core Ethereum projects—improving py-evm, eth-tester and Trinity networking—demonstrating deep protocol-level understanding beyond typical exchange engineering. He’s driven measurable impact: slashing page load times from 30s to 1s, raising API test coverage from 0% to 60%, and leading infra optimizations and CI/CD migrations. A natural mentor and communicator, he shares knowledge through technical articles and YouTube content to inspire engineers. Notably, his open-source fixes include CREATE2 and PAYGAS logic in py-evm and robustness improvements to libp2p PubSub edge cases, reflecting both security-conscious and pragmatic coding.
