About

Software developer from the Oberbergischer Kreis

I'm Antonio Kusmenko, a certified application developer (Fachinformatiker Anwendungsentwicklung), self-employed since 2025 and working for small and medium-sized businesses. I trained at a software company in Lindlar that builds software for car dealerships. Today I build websites, connect systems through APIs, and automate processes that used to run by hand.
