About
Developer from Germany. I build Formfeed on my own: an API that turns templates and JSON into PDFs, e-invoices and images, for code and for AI agents. What I care about: documents checked where they're made (ZUGFeRD / Factur-X, PDF/UA, PDF/A), templates that live in Git with tests, and errors that name the rule that failed instead of just saying something did. I'm here to see what other makers build, especially developer tools, APIs and anything around invoicing and automation. Happy to talk about PDF rendering, Chromium's print quirks and e-invoicing in Europe.
