HPC and infrastructure engineer, finishing my degree at Polytech Paris-Saclay (Sept 2026), open to roles from January 2027 in HPC or infra/DevOps, Paris or Bay Area. I make a GPU kernel fast and keep the production cluster that runs it healthy.
Public handle Kerboul / DaKerboul. Name on the record: ORCID 0009-0003-1770-8830.
GPU energy-measurement tooling for Kokkos, the US Department of Energy's performance-portability framework. The periodic-sampling daemon is merged upstream (kokkos-tools PR #300); the work was presented as a poster at the 2025 Smoky Mountains Conference and written up in an ORNL report.
EDF Lab Paris-Saclay - HPC apprenticeship (2023-2026) C++ memory-profiling and CPU-timing tooling for COCAGNE, a ~500k-line reactor-core simulation codebase.
Sentinel cluster - self-hosted production 5-node Proxmox cluster, ~20 public services behind one Traefik + Let's Encrypt TLS, deployed with Docker and CI/CD with image scanning and automatic rollback. On call for uptime, backups and certs. Live status at kerboul.me/cluster.
