Favex

A crypto app serving around 50,000 users across digital asset trading, gift cards, instant swaps, and utility payments. Worked as part of the engineering team, initially maintaining the existing application by fixing bugs and improving the mobile experience before moving into development of a new version from the ground up. The new application was built with Flutter for iOS and Android, with native Swift and Kotlin used where needed. The work covered core experiences including wallets, transactions, trading, gift cards, and bill payments, with a focus on keeping the app fast, stable, and reliable for users.
