Co-founder and product builder. I co-founded SchaperDaux, an embroidery and printing company near Berlin, and built its entire digital product, from a customer catalog app and a custom CRM to an AI multi-agent system that ran daily operations. I build with AI-native tools, I learn by making, and years of customer contact taught me to really understand what people need.
