Summary
🤩
Rockstar🎓
Top SchoolStéphane Glondu is a seasoned technology leader and CTO based in Nancy, France, with 26 years of experience bridging research-grade engineering and product-focused development. He is a longtime expert in electronic voting systems, having been the principal developer of the Belenios project during a decade at Inria and later shepherding innovation as CTO at VCAST. His hands-on open-source contributions span core OCaml projects—improving Lwt concurrency primitives, maintaining Unison compatibility, and debugging the Coq-based Rocq prover—demonstrating deep expertise in formal methods and reliable backend systems. Stéphane pairs a PhD-level academic background from Université Denis Diderot and ENS Cachan with practical R&D and startup experience, including a year in Inria’s Startup Studio for Z-VOTE. Colleagues know him for turning formal verification and cryptographic primitives into maintainable, production-ready code and for spotting subtle compiler and concurrency issues before they surface in production.

rocq-prover/rocq
Apr 2007 - Nov 2013
The Rocq Prover is an interactive theorem prover, or proof assistant. It provides a formal language to write mathematical definitions, executable algorithms and theorems together with an environment for semi-interactive development of machine-checked proofs.
