Just completed another MVP UI for a banking app, let me know what you guys think about it.
Looks clean. I like the balance card and the weekly spending chart — the UI feels really smooth for a banking app.

Payment Lifecycle Integration Backend
This project focuses on a backend problem I care about a lot:
how to keep an internal payment workflow correct when the external provider is asynchronous and outside your control.
The system models:
· explicit payment state transitions
· idempotent create requests
· webhook-driven updates
· audit logs
· reconciliation for recovery

Interesting project. Payment workflows can get tricky, so this is a cool problem to tackle.
