Orbital Wallet: digital wallet / mobile banking

React Native · Expo · Swift · Kotlin · C++

• Primary author (~2,300 commits): architecture, design system and 7 end-to-end money flows: transfers, bank aliases, QR payments, bill payments (Bancard), signup, password change and account closure.
• Launched the app on the App Store and Google Play from zero; own releases, OTA updates and App Review.
• Built a native document-capture module in Swift, Kotlin and C++ (Nitro Modules) and a full KYC onboarding with liveness check; migrated KYC providers without interrupting signups.
• Account-recovery flows across the wallet API, support chat backend and agent console: authorized retries with locks, pre-login push notifications, idempotent completion.

POS platform and data

Python · AWS Lambda · DynamoDB
