Rockstar🎓
Top SchoolGauthier Segay is a software designer with 17+ years of experience specializing in .NET and functional-first system design, currently shaping forecasting and planning tools for the electricity market at LCG Consulting. He blends customer-focused product design with hands-on implementation, driving feature delivery, technical debt reduction, and improved collaborative processes in brownfield environments. A strong proponent of static analysis, metadata-driven invariants, and functional programming (notably F#), he has contributed to high-profile open-source projects including the F# compiler, Paket, and Fantomas. His background spans consultancy and product engineering for major French enterprises, and he routinely takes initiative to manage risk while modernizing legacy codebases. An often-overlooked strength is his compiler and build-infrastructure experience, which he leverages to improve developer tooling and robustness across teams.
