About this gig

Looking for something custom-made or very specific? Then you are at the right place.


My strong suits are...

  • Java (cross-platform server/app/web development)
  • C/C++ (native application development)
  • SQL (database design, development, and management)
  • JavaScript/HTML/CSS (static/dynamic website development)

-> other languages work too, but have no efficiency discount


I started developing software in early 2019, and working professionally since 2022.

I can speak English and German, and know the basics in Portuguese, Türkish, and French.
