Overview
Integration of the Wero payment feature into BNP Paribas' banking app, replacing Paylib — the most significant and complex project of my career.
Challenge
Replace Paylib's "Send Money" experience while preserving the habits of traditional banking customers, and introduce QR-code-based payments to users who had never used a neo-bank.
Process
- ·Discovery: stakeholder workshops, user interviews, competitive benchmark
- ·User research & in-person testing with diverse banking profiles
- ·Full user journey mapping across all Wero entry points
- ·High-fidelity prototypes + custom graphic assets & illustrations
- ·Multi-brand developer handoff (BNP Paribas, Hello Bank…) via Figma/Zeplin
- ·Pedagogical UI to onboard users unfamiliar with QR codes and money requests
Results
- ✓Exceeded Paylib's user adoption and transaction volume in the first months after launch
- ✓Strong comprehension even from users who had never used QR codes — proven by in-person testing
- ✓Seamless multi-brand rollout across BNP Paribas group
