Pyra is a Solana-based fintech platform that pairs a traditional banking experience — cards, virtual accounts, payments — with on-chain yield and collateralised credit. Brought on as the team's first outside hire, I took ownership of rebuilding the mobile app from the ground up.
I built and owned the core surfaces end to end: onboarding and KYC, biometric and passkey authentication, card management, virtual accounts, payments, and the portfolio and credit flows — wiring the React Native app to Solana through the Pyra Labs SDK and an embedded Privy wallet.
Alongside feature work I owned performance optimisation and release management — EAS builds, OTA updates and store submissions. Over ten months the platform scaled from roughly $50K to more than $4.8M in volume.
