About

I'm a fullstack engineer who builds complete products — from database design to production deployment. With 17 years of hands-on experience and an MSc in Computer Science, I don't just use frameworks; I understand what happens underneath. At Routescanner, I led a team of 5, built all masterdata applications, initiated hackathons to explore ideas, refactored the canonical data model for maritime schedule processing, and sat in commercial meetings to give technical impact assessments on new epics.

My approach: first make it work, then make it better, then make it pretty. At bol.com, I was the sole frontend developer serving 4 teams that grew to 8 — I coached developers across those teams, introduced AngularJS as a new framework, and built the component library that gave all teams consistent, faster delivery. Getting that approved meant presenting to management and navigating the politics myself. At Rabobank, I built multiple mortgage modules and laid the foundations for a framework migration.

I also build my own products from scratch: MovingPolygons (animated GIS), Core-View (AI personality assessment), EUtaxes, Bliply, and more — conceived, designed, built, and shipped solo. I use AI as an accelerator in my workflow, but I review every line. I understand why code works, not just that it works.

Chris is a highly skilled frontend engineer. He knows how to balance technological solutions with delivering actual business value. He has a very strong drive to work agile and in the spirit of the lean start-up. Delivering business value is his main driver.

Jaap CoomansSoftware Architect, GROUP9Worked on the same team

He was able to quickly learn our technology stack and immediately perform as a productive team member. Chris brought real leadership to the team. He was able to coach his peers and work with the bigger context of the scrum team to manage expectations and make better informed decisions.

Roel Kerkhofs, PhDManager Cyber Security, Port of RotterdamManaged Chris directly

What stood out to me is his pragmatic approach to product development. Chris also took the responsibility in mentoring me in the front-end field. Besides learning together, narrowing down the most important features to quickly build software that adds value and solves problems is something non-technical I learned from him.
