Finapp is a personal design engineering project: I designed and built a web demo for the people handling payments, identity reviews, disputes, and support behind a fintech product. The central design task was connecting monitoring to investigation, so the demo brings review queues, transaction details, escrow records, and compliance history into one workspace. I used recurring patterns such as search, filters, status labels, adjustable tables, and side panels to keep context visible as someone moves between records. The live demo is browsable and uses fictional customer and financial data.
