Rockstar🎓
Top SchoolMason Liang is a software engineer with 11 years of experience building backend systems and cryptographic tooling from San Francisco. He currently develops at 0x Labs and has prior engineering roles at Google and Dropbox, bringing experience across high-scale product engineering and research-driven development. Mason’s work in open-source privacy-scaling projects shows deep familiarity with EVM internals and zero-knowledge circuit implementation, including opcode-specs and state-circuit constraints for zkevm. His background blends an electrical engineering BS from Princeton with an MA in Statistics and a PhD in Computational Biology from UC Berkeley, enabling a data-driven, systems-level approach to problem solving. Notably, he pairs production engineering with formal specification work—improving tests, refactoring circuits, and tightening state transition guarantees in blockchain tooling.
