If it can be done, I'll build it.

Websites, web apps, API integrations, accessibility and AI exploration. Below you can read, for each service, what you get, who it is for and what I have built with it.
01 / websites

Websites that bring in customers

A fast, findable site that turns visitors into enquiries, with an admin area where you edit texts and photos yourself.

Who it is for: self-employed professionals, practices and small businesses with an outdated website, or none at all.

What you get

  • Custom design in your brand style, in light and dark theme
  • Fast, mobile-friendly and accessible (WCAG 2.2 AA)
  • Findable in Google: titles, descriptions, sitemap
  • Findable for AI assistants such as ChatGPT and Perplexity: structured data and an llms.txt
  • Edit your own texts in a simple CMS
  • Multilingual where needed, for example English and Dutch

Built: K-TEG, Collibri Transport, Mie Fiesta

02 / custom web apps

Software that works the way your business works

Customer portals, planning tools, configurators and dashboards. For when spreadsheets, emails and separate tools are no longer enough.

Who it is for: businesses with a process no off-the-shelf software fits.

What you get

  • An app built around the way you work
  • An admin area for your team
  • Automatic emails, text messages and reminders
  • Tested and built on Laravel, ready to grow

Built: Gymna, MediFootz

03 / api integrations

Making your tools work together

Web shop, till system, accounting or CRM exchanging data automatically. No more double work, no more typing errors.

Who it is for: anyone keeping the same data in two or more systems.

What you get

  • Custom integrations through the APIs of your software
  • Alerts when a sync fails
  • Maintenance when a supplier changes its API

Built: Webbureau Batman

04 / accessibility

A website everyone can use

I build to WCAG 2.2 level AA: enough contrast, fully usable with a keyboard and clear for screen readers. Since 28 June 2025 the European Accessibility Act (EAA) applies to many web shops and online services for consumers. Not sure whether it applies to you? We can look at it together.

Who it is for: anyone selling or offering services online, and everyone who does not want to shut customers out.

Ask for an accessibility check

What you get

  • Accessibility check of your current site, with a report in plain language
  • Targeted fixes, or a rebuild where that makes more sense
  • Automated tests that check accessibility with every change
  • Help with your accessibility statement

Proof: this website. Read the accessibility statement.

05 / new · in research

AI exploration, without the hype

I look into where AI really saves time in your processes, for example with quotes, emails or documents. You get honest advice: build it, wait, or don't.

how I work

How every project runs

  1. 1

    Free intro call

    You tell me what you want to achieve. I ask questions until it is clear, usually online.

  2. 2

    Clear proposal

    What I will build, what it costs and when it is ready, broken down per part.

  3. 3

    Build & show

    You see what is ready along the way and can steer before it is finished.

  4. 4

    Live & improve

    After launch we keep improving, as separate jobs or through Collisa Care.
