The brief
Mobile money is how millions of people in Rwanda pay every day, but splitting bills, dialling USSD codes and finding receipts in SMS threads is still fiddly. Pebla's redesign had to unify pay, split, history, utilities, referrals and loyalty in one app, without breaking a production backend already serving live users.

Demo
Needs we met
What each group needed for the project to count as a success.
Business
Sit on top of MTN MoMo and Airtel Money instead of replacing them, and give people a reason to pay through Pebla every day.
Stakeholders
The redesign had to keep every production feature working, from eKash and SIM selection to scan-to-pay, and match the real backend contract.
Customers
People wanted to pay, split and top up in a few taps, and to see an accurate history without digging through SMS.
How we delivered
Before merging, every production branch was audited against the redesign with a feature checklist, so nothing live regressed. Where the backend differed from its docs, the app was aligned to the real endpoints and the remaining gaps were written up as an API requirements spec for the backend team.
