About me

Hi, I'm Tim.

Freelance developer who loves building things that don't exist yet.

I build software for businesses: web applications, websites and AI solutions that fit exactly how they work. I also develop games under my own studio, 1Time Games.

That combination is my strength. Game development teaches you to prototype fast, test endlessly and think from the player's point of view. Web development teaches you to build reliable systems that last for years. And AI lets me do both faster than ever.

You work with me directly, with no account managers or extra layers. I help you figure out what you really need, even if that's less than you expected. And I'm good company over a cup of coffee or a craft beer.

01/Values

What I stand for

  • Custom over standard

    Software should adapt to you. You shouldn't have to adapt to it.

  • Fast and concrete

    I'd rather show you something that works within days than spend weeks planning.

  • Honest

    I'll tell you when something isn't needed or can be done smarter.

  • Ownership

    Your code, your data, your product.

1Time Games

My game studio, where I develop my own titles like Nederfall. What I learn there about gameplay, performance and user experience, I bring to client projects.

Got an idea? Let's build it.
