Revisium is a focused SaaS product for German home-care providers. It automates the matching of incoming payments to invoices and turns a process often handled through spreadsheets and manual checks into a structured workflow.

I developed Revisium from the initial product concept through to a production system used in day-to-day accounting. The application imports payment and invoice data, automatically matches clear cases, keeps open items transparent and surfaces only ambiguous cases for manual review. My work covers product design, frontend and backend development, data processing, infrastructure and customer-specific integrations.
