Freelance Full Stack Software Developer · Vienna, Austria

I'm a freelance full stack developer based in Vienna, building web and backend applications since 2018. My work spans React frontends, .NET backends, and the full cloud/CI-CD stack in between — for clients ranging from retail giants to AI startups.

I also teach at WIFI Vienna — JavaScript, HTML, CSS — which keeps me sharp on fundamentals and reminds me what it's like to learn something for the first time.

My background is in architecture (MSc, TU Vienna), where I got deep into computational design and AI-generated floor plans. That systems-thinking mindset stuck — I brought it straight into software.
