Custos Aerarii
A lone campaign, raised end to end — a dedicated iOS app whose frontline is React Native and whose keep is a backend of its own making, holding every user in and their ledger current.
- I
Architected and built the whole ecosystem solo: React Native on the frontline, a robust backend governing authentication and data persistence.
- II
Designed secure RESTful APIs and database schemas that centrally store recurring subscriptions, utility bills, and credit-card installment records.
- III
Shipped an interactive financial dashboard and an automated, iOS-optimised push-notification system — real-time monthly overhead, alerts before a payment falls due.
