Sole mobile developer on a

Sole mobile developer on a confidential greenfield React Native/Expo fintech app, built from scratch across 12+ screens.

Architected the full mobile layer: Expo Router with protected routes, biometric authentication, and secure local storage. Built a custom Expo config plugin to integrate a KYC identity verification SDK. Implemented Web3Auth key management and Solana transaction signing for minting compressed NFTs, with an encrypted local cache layer to optimize repeated crypto operations. The app connects to the Solana blockchain to both read and write data — balances, transactions, and on-chain asset state. Managed server state with React Query, global state with React Context and custom hooks, and integrated 6+ third-party services including PDF handling, Lottie animations, i18n, and Zod validation. Deployed to both App Store and Google Play via EAS.

This is a private project currently in final stages before launch — screenshots available upon request once in production.
