Who I Am

I'm a Software Engineer based in Brussels, Belgium. I specialize in building secure, production-ready web applications for clinical research environments — where reliability and data integrity aren't optional.

My stack runs deep on both sides: Angular + PrimeNG on the frontend, Spring Boot and NestJS on the backend, and a full DevOps pipeline with Docker, Kubernetes, Azure, and Datadog tying it all together.

I like owning features end-to-end — from architecture design and implementation through to deployment and monitoring in production.
