About my work

14+ years online experience as a developer & designer

I am a front-end developer with a strong foundation in design, which leads to better user experiences in less time.

Front-end development

I have extensive knowledge of HTML, CSS & JavaScript (ES6), TypeScript and experience with the 3 most popular frameworks (React, Vue & Angular*). Add ambition, endless curiosity and a GTD‑mindset and you have a pretty complete picture of me.

*I'm not taking on jobs involving Angular or Vue at the moment, sorry!

Digital designer

I speak the designer mumbo-jumbo and dare to make design decisions while coding. This saves valuable development time, endless ping-ponging with designers and often looks even better than the original design. I also do not hesitate to work out something in Figma or Sketch myself.

🔍These are just a few of the technologies I’ve worked with. Are you looking for specific skills? Don't hesitate to ask!

Six things you probably like to know from me

Yes, currently I am available for a new freelance contract. Calling is the best way to get in touch 👉 +316 208 42 105.

My hourly rate is €95 per hour.

I am a real hands-on worker and I am constantly experimenting with new techniques and tools. So I'm used to making things my own quickly. Are you looking for very specific skills? Please contact me to see if I can help you with that!

A few years ago I exchanged the Randstad for green Arnhem in the Netherlands. Is Arnhem too far away from your organization? No problem, I'm used to working remotely. A hybrid model (for example x days in the office) is also possible.

React framework Next.js, TypeScript and Tailwind CSS. The initial draft I built with Eleventy, but moved to Next.js for the nicer developer experience. I’m now thinking of porting it to Astro, which is a much better choice for simple landing pages like this (but didn’t exist in 2020). Why? Astro ships zero JavaScript by default and has great lazy loading capabilities out of the box (and is therefore fast). It’s what I’ve used for the Dash landing page also.

I love trail running around Arnhem where the surroundings are beautiful. I also enjoy playing indoor soccer and watching soccer games. That I also practice meditation and eat vegan probably classifies me as a health nut, but I am a sucker for craft beer ;) (D/T(NE)IPA's!).

In my spare time I like to work on one of my side projects. Dash is one of them; a Figma plugin that helps designers speed up their workflow with search and a simple command UI. I really enjoy making tools that make live just a little bit easier.

Feel free to contact me if you're looking for a communicative front-end developer who is passionate about creating great user experiences or just want to have a chat.
