I code dreams



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, etc. I prefer short iterations and consequently small prices.

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 learning a new language. Tetris needs more concepts than STDOUT: graphics, input handling, data structures, sorting etc.
