At Careem, I redesigned the Food Discovery page in Jetpack Compose and built scalable media modules for dynamic content. I also owned Favorites and shipped it in four weeks, while maintaining 100% test coverage for the code I shipped.

At NymCard, I designed a multi-tenant, multi-module white-label banking SDK from scratch, with OAuth and OpenID Connect authentication protected by Android Keystore. Earlier, I architected FinPocket’s Android trading app from zero, and as an independent engineer I built VisionMax (MaxTrade), a Kotlin Multiplatform trading app now live on the Play Store.
