At easyerechnung.de, I developed and run a live e-invoicing and bookkeeping SaaS for freelancers. It supports XRechnung, ZUGFeRD, DATEV export, and German tax reporting, with more than 150 automated test files.
At tapmy.store, I led a Turborepo monorepo migration that cut build times by 40%, and built an AI chat widget for creator pages. I also integrated booking with Google Calendar and Stripe.
As a freelance Full-Stack Engineer, I’ve delivered more than 20 web applications for B2B clients. My projects include a multi-tenant order-management platform for medical practices and an AI document-processing platform that redacts personal data before model calls.
At tailbook.me, I’m the technical lead for a team of 10 developers working on a React and TypeScript platform. I guide architecture decisions and code reviews, and introduced custom AI agents into the review process.
