Projects
A collection of things I've built: personal projects, school work, and experiments. Search by name or filter by category.
Räppli
A privacy-first budget analyser for Swiss bank statements. Upload a CSV, CAMT, Excel or PDF export and get your spending auto-categorised by 300+ Swiss merchant rules and an LLM, charted, scored and critiqued with concrete saving tips. Runs in the browser, nothing stored.
Bücher Antiquariat
A full-stack PHP web app, branded “Archivum”, for managing the books, customers, and inquiries of an antiquarian bookshop. Public catalogue with search and a complete admin back office.
Notentool
A local-first grade book for students, built in pure vanilla JavaScript with no framework or server. Track semesters, subjects, exams and homework, with weighted averages, plus/minus points and a promotion check, all in the browser. Live demo included.
