Abdallah B.

With 5+ years of experience and a 100% Job Success score, I’ve contributed to Android apps that reached 1+ million downloads with a 4.7 rating. I build production-ready mobile applications for e-learning, AI, e-commerce, health tech, and IoT industries. I specialize in native Android development (Kotlin, Java, Jetpack Compose) and cross-platform apps using Kotlin Multiplatform (KMP), applying Clean Architecture, Coroutines & Flows, and solid unit/UI testing to keep codebases scalable and maintainable. From custom UI and animations to complex integrations like Firebase, REST APIs, Google Maps SDK, and Stripe payments, I handle the full mobile app lifecycle from idea and MVP to Play Store launch and ongoing improvements.
