SafeClawcredential broker for AI agents. An agent that holds your API key holds your full authority, every call, forever; here agents only ever see phantom credentials, a local proxy injects the real secret at the network edge, and sensitive calls wait for a passkey tap that becomes a single-use grant bound to one exact operation. A fully compromised agent still cannot spend your authority.co-founded 2026 · production stack built solo in three months · open sourcesafeclaw.progithubthe paper behind it

~/sky/about/career
since 2026 Co-founder, SafeClaw: an open-source credential broker for AI agents, so agents get scoped, per-use, user-approved delegation instead of reusable secrets. Built the production stack solo: a Rust egress proxy, an end-to-end encrypted passkey-sealed vault, a web console, and a cloud control plane.
2023 to 2025 Technical co-founder of a verifiable-AI infrastructure company. Built and led an engineering team of 10+; research and implementation of core protocols for verifiable AI systems and zero-knowledge-proof infrastructure.
2018 to 2023 Head of blockchain security, Chaitin Tech. Founded and led the practice from zero, one of the earliest such teams in China. 100+ zero-day vulnerabilities across the consensus, P2P, and verification layers of major blockchains; roughly 1M lines of code audited; 5 CVEs from smart-contract audits.
