About Me



I am Joris Zwart. Creating things using my skills in software development is my game.


I do fixed-price projects in the field of 2D/3D visualization, integration, APIs, reverse engineering of file formats, writing components and many more.

I prefer short iterations, consequently small prices and believe that each iteration should add real value.


I live in a small village near Nijmegen in the Netherlands with my lovely family.


Go and JavaScript/TypeScript are my languages of choice, but I also have 15+ years of experience with C# and Java.

In my spare time I meditate by pixeling and coding on the Commodore 64.

Why so many Tetrisses?

Because I think “Hello, world” does not cut it when experimenting with a new language. Tetris needs more concepts than STDOUT: graphics, input handling, data structures, sorting etc.
