Senior🎓
Top SchoolSeth Fowler is a senior software engineer with 15 years of experience building high-performance, privacy-respecting infrastructure that powers the web and cloud networks. He has driven performance and energy-efficiency improvements in browsers at Mozilla and Qualcomm, built compiler and toolchain components for programmable network processors at Barefoot Networks, and led core engineering and privacy-by-design efforts at Fullstory. At Fullstory he combined machine learning and user-centered design to deliver patented “Private by Default” capture and large-scale redaction tooling that unlocked regulated markets. His open-source contributions to the P4 reference compiler show a deep attention to correctness and low-level performance tradeoffs, including fixes for GMP-related lifetime bugs and template optimizations. Now based in Portugal and currently at Datadog, he thrives in small teams tackling hard systems problems and prefers solutions that respect users’ time, dignity, and privacy.

Contributions summary:Seth contributed to the P4_16 reference compiler by fixing a bug related to GMP types and lambda functions. They added explicit return types for lambdas returning GMP types to resolve an issue where the GMP values outlived their stack frame. Furthermore, the user reduced template instantiation overhead in JSONLoader and optimized compilation by storing raw function pointers. These changes indicate a focus on performance and code correctness within the compiler's core functionality.
