Pago — React Native Mobile Engineering
Built the original mobile app and led its implementation as the team grew: payment and card workflows, native integrations and production releases.
From the original app to team leadership
At Rubicon, I built the original React Native Pago mobile application and led mobile implementation as additional developers joined. My work connected onboarding, payment and account-management interfaces to backend services.
Mobile workflows and native integration
I implemented authentication and recovery flows, KYC/ID verification interfaces, transactions, QR and NFC functionality, native bridges, statements, contact synchronization, profiles and transaction categorization.
Card workflows included verification, blocking and pausing, with transaction PIN-verification flows developed in collaboration with backend engineers.
Application architecture and delivery
I implemented global and local state management and persisted selected data to reduce startup server fetches. I reviewed pull requests, guided development and trained incoming developers, while working on CI/CD, app-store releases and production support.
This case study covers my work on the original React Native application, before later product rebuilds.
