Wink
Costa Rica's first neobank, delivered through a React Native mobile app, AWS backend, partner-bank APIs, and biometrics.

Wink is Costa Rica's first neobank: a mobile app for banking without a branch visit. I built the first version of the app and the AWS backend it depended on.
I chose the stack, planned the work, and coordinated partner-bank API integration. I also implemented biometric authentication so KYC and login did not need a branch visit.
Launch required forming a development team that did not exist yet.
Achievements
- Developed the first version of Wink's mobile banking app.
- Integrated partner-bank APIs so deposits, transfers, and account data could move through the app.
- Built biometric KYC with a React Native native bridge.
