I will modernize your existing application

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.
