I build businesses. My career is a mix of high-growth startups, hard-learned failures, and leading architecture for Germany's biggest FinTechs.
The Track Record:
- Entrepreneur: Founder of PepStack (Biohacking OS), Blastin (Event Ticket Reselling), Forge (Training), BloodBuddy (Smart Bloodwork Tracking for Everyone), and previously Smaboo (Small Business Booking Platform). I know the ups and downs of the founder journey firsthand.
- Flutter Authority: Built the largest German Flutter course on Udemy with 10,000+ students. I've been using Flutter since day one.
- Architect for Enterprise: I support major German banks and financial institutions in mastering complex software architecture, security, and compliance. In my many Years in Fintech it automatically happened that I always slide into the lead as I take full Responsibility for the Success of the Project.
How I Help:
I’m a Growth-Focused Freelancer. I bridge the gap between "Out of the box" startup thinking and "Rock-solid" enterprise quality.
Whether you need a Software Architect to save a failing project or a CTO-level partner to scale your MVP:
I focus on execution and mastering the latest tech AI-driven workflows. My Skills are far beyond Development - I bring Ideas and not only Refactor Code but also Lead Your Business to Success.
If you need someone who understands both the code and the P&L — let’s talk.
