PROFILE
Laurent Perron
Laurent Perron developed and maintained advanced build and integration workflows for mathematical programming libraries in the grpc/bazel-central-registry repository over six months. He engineered Bazel-based build system configurations for C and C++ projects, integrating solvers such as SCIP, Soplex, Highs, and Papilo, and ensuring compatibility across Bazel versions and platforms. His work included dependency management, patching, and the introduction of automated CI validation and presubmit processes, which improved build reliability and reproducibility. By upgrading solver dependencies and implementing parallel presolver support, Laurent enabled scalable, maintainable builds and streamlined onboarding for downstream consumers and contributors in mathematical optimization projects.
