01 · About

I'm a passionate engineer in a continuous quest for improving the efficiency of things I see around me. I'm highly committed and goal-oriented when something captures my interest, and you can always make my day with a conversation about IoT or home automation.

In my spare time you can find me on my bike, at my computer, or planning a backpacking journey to explore a new part of our planet.

Belfius

  1. Lead Engineer2026 – Present
  2. Senior Engineer2023 – 2026

Engineering in Belfius Technology, one of Belgium's largest banks: modernising how critical banking systems, cloud applications and external services talk to each other.

Projects

  • Architected and developed a cloud-native integration platform modernizing communication between critical banking systems, cloud applications, and external services. Designed a scalable, distributed architecture leveraging Java, Spring Boot, and Kubernetes.

    Applied platform engineering principles by developing a custom Kubernetes Operator, enabling declarative configuration, automated lifecycle management, and developer self-service. Leveraged Helm and Kubernetes-native automation to simplify enterprise integrations and streamline software delivery.

  • Pitched an idea, built a working prototype through the night and presented it to a jury from Belfius management and Mistral AI.
