Custom web development in WordPress and Laravel

Websites, webshops, web applications, plugins and integrations. For websites and webshops I can take care of the whole process if you like, from design to maintenance. I also build custom work and give advice on technical questions. Always with the same aim: work you can rely on, and a working relationship that lasts for years.

Frequently asked questions

Who do you work for?

For companies and organisations that take their website or application seriously, and for agencies looking for a senior developer. From the University of Twente and Giro555 to businesses with a webshop or an application of their own.

I don’t know exactly what I need yet. Can I still get in touch?

Especially then. Tell me what you want to achieve, and I will help think through the approach and tell you what I would do and why.

Do you also do the design?

I leave the design to specialists. For that I work with regular freelance designers, such as Ivo Ruijters of Around Seven. You can also bring your own designer. Either way, I remain your point of contact and think along from the start about what works well technically.

How do you work with agencies?

In two ways. I work directly for your client and invoice them myself, or I work for you and you invoice your client. Either way, the client remains yours, and the client knows I am working on it as a freelancer.

What does it cost?

That depends on what needs doing, and projects of any size are welcome. You get a fixed price as soon as the brief is clear. Smaller jobs are billed by the hour.

I develop websites, webshops and applications in WordPress and Laravel, and have since 2011, for clients including the University of Twente, Giro555 and iCulture. Most clients have worked with me for years.

Tell me what you want to achieve, and you’ll hear from me personally what I would do. Even if you don’t know yet exactly what you need.
