About

I’m a backend software engineer at Picnic in Amsterdam. I have more than six years of professional experience, mostly working with Java, Spring and distributed systems at Picnic and American Express.

At work, I’m interested in backend architecture, reliability, observability, messaging and the practical side of running services in production. I also spend a fair amount of time thinking about how engineering teams can use AI tools without lowering their standards or losing ownership of the work. Outside work, I enjoy travelling, reading, music, films and going to the gym. I have been learning Japanese for the past few years and take a weekly lesson.
