Hi, I'm Pierre.
Embedded Systems & DevOps Engineer. I write about the things I build and break: CI/CD pipelines and containers on one side; firmware, embedded Linux and the hardware it runs on on the other, plus the infrastructure that keeps it all running.
Infrastructure
Linux servers, Kubernetes and Nomad clusters, Ansible, networking, VPNs and self-hosting.
DevOps
CI/CD pipelines, containers, self-hosted runners, release automation and observability.
Embedded Systems
Firmware, RTOS, embedded Linux, Yocto, bootloaders, drivers and debugging on real hardware.
