About Me

I'm a Software Engineer who builds reliable, scalable systems with Java and Spring Boot (or Python) . I'm a well-versed multidisciplinary developer covering the full lifecycle from a technical or functional point of view.

Designing, developing, optimizing and shipping applications or API's.

Data modelling, deploying, tuning and monitoring databases with safety in mind (intrusion detection and prevention and auditing).

Critically evaluate and guard techical design decisions explain the constraints and trade offs in a clear manner.

Building observability solutions for mission critical applications and/or data (guarding data quality).

Owning the full run of production deployments and stepping in when it matters.

Setting up a cost effective and resillient cloud-native services on AWS and Azure

I thrive on technical puzzles and keeping distributed systems running smoothly. I'm always looking for ways to innovate, learn, and grow 🚀

When I'm not coding, you'll find me at the gym, on the soccer field, or riding my motorcycle through the Dutch countryside.
