Summary
🤩
Rockstar🎓
Top SchoolLucas is a Distribution Engineer based in Tokyo with 11 years of hands-on experience building and shipping networked systems and tooling. He has a strong backend and systems engineering background demonstrated by contributions to well-known open-source projects like shadowsocks and a native Go TUN/TAP library, where he added Windows support, UDP handling, and performance-focused I/O improvements. Prior roles include senior engineering positions in Japan and a current distribution role at GitLab, reflecting a mix of product-facing delivery and low-level protocol work. His academic grounding from the University of Tokyo and earlier telecommunications training in Beijing underpin a pragmatic approach to cross-platform networking and build systems. Colleagues value his knack for fixing subtle platform-specific bugs—DNS and macOS quirks among them—and for improving developer experience through clearer docs and safer refactors.
