About me

Since the age of 14, I was interested in creating websites and starting online businesses. Sometimes I started my own projects / companies, other times I worked as a freelancer. Nowadays I am CEO of the company I founded: Rompslomp.nl B.V.. As long as I'm working on great working consumer focused software, I'm happy.


I work as a full-stack developer on the backend as well as the frontend. Besides Ruby on Rails, I work on Node.js / React / React native apps. I'm passionate about TDD (Test driven development) and always work in an agile way with an eye for great UI.


I prefer to work on exciting and challenging projects (who doesn't?!). My office is in Utrecht, from where I work remotely. From time to time I work on site too (in the Netherlands, some of the projects I did were in Utrecht, Amsterdam, The Hague and Rotterdam). Contact me to have a coffee and talk about your project.

Projects i've worked on

Rompslomp

Rompslomp

Rompslomp is my life's work, a very simple intuitive accounting solution focused on the Dutch ZZP market. I started Rompslomp back in 2011 to scratch my own itch working as a freelancer. In 2014 together with my business partner Niels Koning, we incorporated Rompslomp.nl B.V.. Over the next years, we grew the company into a team of 12 people after which the company was acquired by Visma in 2022.
