About Me
I'm a Full-Stack Developer who builds business software end to end: ERP systems on SAP HANA and Node.js, healthcare and driving-school platforms in PHP, and now AI automation with Claude and n8n.
I led a development team at Adaptech LLC, with a background at Dedalus GmbH too. I now support Deutsche Telekom's B2B sales platform at SELISE Group, and built a support platform solo that replaces several inboxes and a manual ticket process.
I work daily in German and English, and I take projects from idea to production.
