Hi, I'm Tim.I build digital products.
Independent product builder and software developer based in Amstelveen. I like working close to the problem, deciding what actually makes sense to build, and then taking responsibility for getting it into production.

HOW I WORK
- DIRECT
If an idea is unnecessarily complicated or expensive, I say so before it becomes code.
- CLOSE TO THE PRODUCT
I work directly with the people who understand the business, not through a ticket queue.
- END TO END
Product decisions, UX, frontend, backend and launch are one job, not five handovers.
- AI WHERE IT HELPS
I use AI heavily where it genuinely helps; responsibility for the architecture, code and result stays with me.
Where that experience comes from.
