Encrypt Sim App

Overview

Encrypt Sim App is a secure eSIM mobile app with Solana wallet login and a built-in VPN — pairing connectivity with privacy and on-chain identity. As Mobile Engineer on a 3-person team, I architected and refactored the entire React Native/Expo codebase, and built the wallet-connect and secure login flows. Bringing structure to the codebase made the app more stable and easier to extend, while wallet-based login gave users a self-custodial way to sign in and manage their eSIM securely. The focus was security and maintainability: a cleaner Expo foundation and authentication flows built around a Solana wallet rather than traditional credentials.
