Summary
🤩
Rockstar🎓
Top SchoolChih-cheng Liang is a developer with 11 years of experience based in Taiwan, specializing in backend systems, blockchain tooling, and protocol-level engineering. At Ethereum Research he contributes to core projects and has a strong open-source footprint—work spans zkevm specs and circuits, py-evm, Trinity, and libp2p—demonstrating expertise in EVM internals, zero-knowledge circuits, smart contracts, and network stacks. He has implemented low-level numeric and opcode logic, refined smart contract vote validation, and improved cryptographic circuit components, showing both correctness-focused engineering and practical testing discipline. Comfortable across Python and TypeScript, he also bridges research and application as a data scientist and full-stack contributor on MACI and other privacy-scaling projects. An attention to detail is evident from type-hinting, refactors, and writing clearer contract logic—skills that help harden protocol implementations used by the Ethereum ecosystem.
