Websites and apps for your business.

I'm Sjoerd, a freelance developer in The Hague. I build new websites and apps for iPhone and Android, and maintain existing ones. I work with clients from the Netherlands to Japan.

what I do

Services

New websites and apps, and help with software you already have.

Websites and web apps
From a company website your team updates themselves to a platform with accounts, payments and search. It works on phone, tablet and desktop.
Apps for iPhone and Android
One app that runs on both. For your customers, or for your own staff, for example to replace paper forms.
Support & maintenance
I take over software someone else built. I fix what's broken, add what's missing and keep it up to date.
step by step

How I work

What working together looks like, from the first conversation to launch.

01

Intake

You tell me what you need. We go through it together, without obligation.

02

Plan and price

You get a plan for what I'll build. A fixed price when the scope is clear, an hourly rate when it isn't.

03

Build in phases

I build in phases and show you the result after each one, so your feedback goes straight into the work.

04

Launch and after

After launch I can keep maintaining the software, or you take it over yourself.

Client feedback

What clients say about working with me.

“I needed someone who could clearly understand what I needed and translate it into a functional and user-friendly website. Sjoerd understood the purpose behind the website instead of just seeing it as a project. He was communicative, responsive and incorporated feedback seamlessly. The result is a well-functioning and attractive platform built exactly around its purpose: helping exchange students worldwide find housing abroad.”

“He helped me every step of the way and explained everything that needed to be done, which made the whole process quite straightforward. He was always very clear about what was and wasn't possible. There was a little bit of trial and error, but I think that was needed to get the website that I was wanting.”

“We needed a completely new website that would do justice to our new positioning and product range, and it had to be ready in a short time for a trade fair. The collaboration went very smoothly and communication was particularly pleasant. We're very pleased with the result: a really nice look and feel, completely different from before, and our product range is presented strongly.”
