Zurich, Zurich, Switzerland
Summary
🤩
Rockstar🎓
Top SchoolJesse Rosenstock is a seasoned software engineer with 11+ years of professional experience and a long tenure at Google, based in Zurich. He focuses on backend systems, performance engineering, and low-level tooling—contributions include improving Google’s s2geometry spatial library and hardening the google/benchmark microbenchmarking library for cross-platform stability. Jesse has a strong systems background demonstrated by work on the cc65 C compiler (bit-field handling, refactors and tests) and thorough test and performance-focused contributions to projects like pokerstove. He blends practical engineering with careful maintenance: merging large upstream codebases, modernizing legacy C/C++ code, and adding coverage through tests. Educated at Caltech and Carnegie Mellon, he pairs formal CS training with a patient, detail-oriented approach to reliability and cross-platform correctness. An unstated strength is his knack for safely integrating divergent code branches—useful in long-lived, multi-version codebases.
