Summary
👤
Senior🎓
Top SchoolSylvain Bauza is a seasoned cloud and systems engineer with 13+ years building and operating large-scale web and OpenStack environments, now serving on the OpenStack Technical Committee and as a Principal Software Engineer at Red Hat. A long-time Nova core contributor and former Nova project team leader, he specializes in compute scheduling, resource management (including vGPU workflows), and hardening API client surfaces—work visible in high-profile repos like python-novaclient and nova. He blends hands-on development (Python, CI/CD, orchestration) with operational leadership, having run production SaaS platforms and led cross-functional teams engaging partners such as NVIDIA and AMD. Sylvain’s background spans both low-level reliability (HA, DRBD, Pacemaker) and cloud-native features (auto-scaling, virtual GPUs), giving him rare end-to-end expertise from hardware to API. Not obvious at first glance: he has repeatedly navigated the tension between upstream open-source design and customer-driven product needs, mentoring teams while still delivering code that fixes race conditions and subtle scheduling bugs. Based in Le Versoud, France, he pairs academic foundations in computer science with practical production experience across telecom, media, and enterprise clouds.
