Guillaume Pinot is Head of Optimization with 12 years’ experience applying operations research and combinatorial optimization to transportation, scheduling, and human resources planning. He holds a PhD in computer science and has moved seamlessly between academia and industry, solving multi-objective and uncertain scheduling problems and leading R&D teams. Guillaume pairs deep theoretical expertise (branch-and-bound, constraint programming, metaheuristics) with hands-on systems work, contributing performance and memory optimizations to notable open-source projects like Valhalla and the Rust geo ecosystem. He has practical embedded and back-end development experience in Rust, including work on the widely used clap and protobuf toolchains and a Rust keyboard firmware. Known for reducing allocations and fixing subtle algorithmic bugs, he brings an engineer’s focus on efficient, maintainable implementations of complex models. Based in Greater Paris, he now leads optimization efforts at Pelikan Mobility, turning advanced algorithms into production-ready routing and planning solutions.

The open source software to build cool stuff with locomotion

Role in this project:

Back-end Developer

Contributions:1091 commits, 540 PRs, 385 pushes in 4 years 8 months

Contributions summary:Guillaume focused on enhancing the codebase to support various features and compatibility requirements. They implemented preprocessor checks to ensure compatibility with multiple versions of the `pqxx` library, which is related to PostgreSQL. Additionally, they addressed warnings in the code, optimized data handling by creating a memory management system, and made code modifications to support the new features and prevent logic errors.
