Senior🎓
Top SchoolGuillaume Marques is an operations research specialist with 11 years of experience translating advanced mathematical models into production-ready decision software for large-scale infrastructures. Based in Paris, he has led R&D and full-stack development across deeptech startups and public research labs, notably developing Coluna (a Branch-cut-and-price framework) and industrializing a national-scale gas network optimization and simulation tool at GRDF. His work spans Julia, JuMP, C++, Python and commercial solvers (Gurobi, CPLEX), combining exact combinatorial methods from a PhD with pragmatic CI/CD-driven engineering. A finalist for the VeRoLog doctoral prize and an author of highly cited papers, he blends academic rigor with product delivery and has a track record of mentoring teams, recruiting early hires, and shaping validation strategies that proved superior to legacy systems.
