Back to original languageAbout Sebastian
I am a full-stack developer with practical experience – web, mobile, backend, hosting, from the first line of code to live deployment.
With Sovion, I work independently and without overhead: short paths, direct communication, quick decisions. You talk to the person who actually develops – no ping-pong across three levels, no hidden costs. Just clean work, delivered directly.
