Fintech MVP · UPI · Flutter

A UPI-rivalling payments MVP, built UI-first.

For a fintech startup, Nitish built most of the UI and the API integrations for an MVP that reimagined payments around a single unique tag — pay anyone with a "/tag," link and autopay your subscriptions, and stay interoperable with every UPI app.
