Summary
🤩
Rockstar🎓
Top SchoolLaurent Aphecetche is a physicist and seasoned software engineer with 11 years of experience bridging experimental nuclear physics and large-scale scientific software engineering from Nantes, France. With a PhD in Nuclear Physics and a background in scientific instrumentation, he contributes to critical open-source projects for the ALICE experiment at CERN, notably improving MUON calibration code, the O2 framework, and build recipes for alidist and Spack. He combines back-end development, systems architecture and DevOps skills to streamline complex build and deployment workflows and to harden test and visualization infrastructure. Comfortable operating where hardware meets software, he’s known for pragmatic refactoring and integrating online/offline analysis flows—work that quietly enables reliable physics data processing at scale.

ALICE Software Framework
Role in this project:Back-end Developer
Back-end DeveloperContributions:142 commits, 20 PRs, 18 comments in 4 years 6 months
Contributions summary:Laurent primarily contributed to the ALICE Software Framework, specifically within the MUON (Muon Spectrometer) subsystem. Their work focused on improving the code related to data analysis and calibration, including the addition of mean HV value computation and modification of the "Replace" method, which suggests they were working on calibration procedures. The commits also involve integrating changes from the online system to the offline analysis and a general refactoring of the code.
