Hello, I'm Julien.

Software integrator, Linux and embedded systems. I focus on everything that keeps complex environments running: from DevOps infrastructure to embedded integration, through Edge computing and IoT. I deploy, I integrate, I keep things running, on servers, embedded systems, or robotic platforms.

Two angles, one discipline: keeping complex systems running in production.

DevOps : CI/CD, containerization, observability, IaC

EdgeOps : Embedded Linux, IoT, protocols (Matter, Thread, MQTT), ML model integration in constrained environments

About me

My name is KOLANI Julien Yendoupabe, currently finishing a Master's degree in Computer Science and Systems, a joint program between UTBM (France) and the University of Lomé (Togo).

Embedded Linux integration (Yocto/BitBake, cross-compilation, IoT protocols) at Orange Innovation. Virtualized infrastructure administration (Proxmox, Docker, CI/CD pipelines) at a previous employer. Comfortable on Linux systems, with a particular interest in constrained environment integration, continuous deployment, and keeping infrastructure operational.
