Rockstar🎓
Top SchoolFabrice Mouhartem is a Senior R&D Engineer based in Paris with 10 years of experience at the intersection of applied cryptography and full‑stack engineering. He holds a PhD in Computer Science and has moved between academia and industry—working on lattice‑based and post‑quantum crypto at ENS Lyon, PQShield, Microsoft Research India, and IIT Madras before joining XWiki to lead R&D for CryptPad. He combines deep theoretical knowledge of privacy‑preserving protocols with practical software delivery, contributing front‑end and back‑end improvements to the end‑to‑end encrypted, open‑source CryptPad project (notably the calendar and ICS handling). Comfortable in both research and product contexts, he excels at turning advanced cryptographic primitives into usable, auditable systems.
