Summary
👤
Senior🎓
Top SchoolKevin Lalumiere is a backend developer with nearly a decade of experience who currently architects index infrastructure and CI for large C++ codebases at Coveo. He led a complete refactor of a ~1M-line C++ build system, serves as the liaison to security teams, and mentors junior engineers while evaluating dependency manager transitions. Prior to Coveo he built high-performance parallel libraries and CI systems for quantum simulation software, grounded in a PhD in quantum physics from Université de Sherbrooke. An active open-source contributor, he improves Microsoft’s widely used vcpkg and vcpkg-tool—fixing cross-compilation issues, build warnings, and adding binary caching features—bridging developer tooling and production builds. His blend of scientific rigor and hands-on build/CI expertise makes him especially strong at solving complex, cross-platform build and dependency challenges.
