Web development · AI features · automation

I taught myself to code at the age of twelve - at first for video games, later to build things that made my own life easier. That curiosity turned into my profession, which I put on a professional foundation with a master’s degree in computer science: today I automate tedious, repetitive tasks - no longer just for myself, but for entire teams.

What matters to me is not only that a system works on the day it’s handed over, but that it holds up even when it’s maintained less closely down the line. I build projects so that other teams can take them over without trouble - clearly structured, readable, and easy to follow. I’m not a lone wolf who keeps knowledge to himself; I leave behind systems that others can keep working with.

I help teams and founders automate business processes, build web applications, and put AI to use where it delivers real value - with short feedback loops instead of long solo runs, and a clear eye for simple, stable solutions.
