Shipped this project!
I built PennyWise: a personal budget tracker that lets you manage cash, bank cards, and digital accounts in one place. You can log expenses, track income, set recurring bills with due day alerts, and work across 10 currencies with live exchange rates.
The hardest part was setting up the data layer: every change saves to both localStorage and Supabase simultaneously, so the app works instantly on load while staying synced to the cloud across devices.
Most proud of actually shipping it.
