Summary
🤩
RockstarPere Mato is a Senior Applied Physicist at CERN with 25 years of experience combining deep physics expertise and pragmatic software engineering. Based in Geneva, he specializes in back-end development and build engineering for large scientific codebases, contributing to flagship open-source projects like ROOT and the Cling C++ interpreter to improve cross-platform builds, compiler compatibility, and Python bindings. His work focuses on making complex data analysis tools reliable and portable—often by untangling build systems, CMake configurations, and compiler quirks across Xcode, GCC, and clang. Pere’s contributions are pragmatic and detail-oriented, reflecting an ability to translate experimental requirements into stable, maintainable tooling used by the global research community. An understated but valuable trait is his emphasis on build- and deployment-level fixes that quietly enable high-impact science to run smoothly.
