About

I'm a systems architect based in Luxembourg City. My main focus is LuxAIOps: European, sovereignty-first observability with hybrid edge agents, built for teams that can't ship their telemetry to US clouds.

On the side, I ship small, sharp products (LaTeX tooling, finance education), teach Python & SQL, and keep this public notebook: the tech, finance and culture events in Luxembourg I'd actually attend (annotated with my take) plus the planning tools I use myself. Fast, honest, and your data stays in Europe.
