02 / ABOUT

Curious by nature. Builder by choice.

I'm Kai, a software engineering student from the Netherlands, studying in Amsterdam.

I enjoy building software that solves real problems, whether that's a mobile application, backend service or AI-powered product.

At Anchiano, I've gained experience working on production software with Flutter, Spring Boot and spatial data. With Signaly, I've experienced another side of development: building our own product, testing ideas with users and improving both the technology and the business around it.

I'm currently exploring machine learning and Responsible AI as part of my studies, including the group project Smallest Sufficient Model.
