$ whoami

I’m a software engineer and entrepreneur based in Germany, who started writing code back in 2018, building websites and silly games for fun, later for friends and family. Time passed and it turned into a career. What was born out of curiosity became a conviction: technology should be accessible, fair, and built with craft.

That conviction led me to found Callipson, the software development agency that partners with startups and enterprises who deserve better than overpriced, soly vibe-coded or under-engineered solutions. We build apps and systems that actually work.

On GitHub I ship open-source tools, AI experiments, starter kits and some just for fun projects. No hype, no shortcuts, but for the love of doing it.

Vibe Coding is not progress, but technical recklessness. AI may be able to write code that “just works.” But in the end you will be responsible and held accountable for your users and their safety.
