About Guillaume
Spécialisé dans le développement système en C et l’architecture ARM, je concentre mon activité sur les interactions directes avec le matériel. Mon expertise inclut le développement de drivers Linux, la virtualisation et l'utilisation avancée de débogueurs comme GDB et Syzkaller pour l'analyse de crashs et de vulnérabilités.
Co-fondateur d'un laboratoire de sécurité système, j'ai notamment conçu un hyperviseur ARMv8-A et un driver NVMe déterministe pour processeurs RISC-V. J'apporte cette rigueur technique et ma capacité à résoudre des problématiques de bas niveau critiques pour vos projets de systèmes embarqués ou de sécurité.
Je suis à l'aise autant en français qu'en anglais et suis capable de communiquer de manière professionnelle dans les deux langues.

Specializing in C system development and ARM architecture, I focus on direct hardware-software interactions. My expertise includes Linux driver development, virtualization, and the advanced use of debuggers such as GDB and Syzkaller for crash and vulnerability analysis.
As the co-founder of a system security laboratory, I notably designed an ARMv8-A hypervisor and a deterministic NVMe driver for RISC-V processors. I provide the technical rigor and problem-solving skills necessary to address critical low-level challenges in your embedded systems or security projects.
I am fully bilingual in French and English, capable of communicating professionally in both languages to support international collaborations.
