Nikolas Stepan
I'm twenty-three, born in the Czech Republic, raised in Spain and France, and currently in Budapest. I co-founded my first company at sixteen and have been building, directing and selling across three ventures ever since. The day-job has always been: see the workflow that's bottlenecking the business, build the software that removes it, and live with the consequences as a user.
I work across three pillars — cultural events, web & AI, and international sales. They're not separate hats. Each one funds, informs and constrains the others.
I'm looking now for a senior engineering, solutions-engineering or founding-engineer role at a company building something I'd happily live with for years.
"I treat software as infrastructure for the businesses I run — not demos, production systems that are load-bearing for real revenue."
