Based in Stuttgart. Open source is more than a hobby for me. I like building things that people actually end up using.

About Me

Karim Zouine

Hi, I am Karim Zouine. I have been writing code since I was a kid, and I never really stopped.

Based In Stuttgart
Passion Open Source
Open For Selected Projects

Open source is more than a hobby for me. I genuinely enjoy the work, and it never gets old to see something I built turn out to be useful to someone else.

ImgCompress is a good example. It started as a small tool I built for myself, and today plenty of people run it.

“Do good, and good comes back to you” is my motto. I like helping people, so I am always up for a chat about an interesting project or about building software well.
