The story

Delta, a student consulting group at KIT, needed an internal app for its invoices: as PDFs that match fixed templates, and as Factur-X XML.

We were a team of three, building on the T3 stack with Next.js, React, TypeScript and Tailwind. I built input fields and components that follow the XML structure, the backend logic that processes the invoice data, and the PDF designs based on the given sample layouts.

The code lives on Delta's internal GitLab and stays private. The public repository only describes my part and the architecture.
