About Me
Financial Accountant · FinTech & Applied AI
Welcome to my portfolio
Financial Accountant with experience in bookkeeping, VAT filings and preparatory year-end work. On that foundation, I build practical FinTech tools (the open Fin-Tools Hub) and apply AI systems to structure financial data and automate workflows — with clearly defined architecture, full validation, and the responsibility resting with me.
Current focus: Endriss preparation course completed in January 2026; independently preparing for the Geprüfter Bilanzbuchhalter (IHK) examination in September 2026. Qualification not yet obtained.
Working method: I design the product architecture and domain model myself — implementation happens with professional AI coding assistants under my direction and responsibility, with full validation and no compromise on code quality. Human-led, AI-accelerated.
