I build production Android apps end-to-end in Kotlin and Jetpack Compose, from architecture and UI through Firebase/backend integration, Play Store release, and the performance work most projects skip: baseline profiles, memory profiling, and app-size reduction.
Recent work: Arcadia, an AI-powered game tracker that won 1st place in a national Egyptian tech initiative out of 120,000+ participants and is live on Google Play. FlexPing, a background-monitoring app for Amazon Flex drivers, live on Google Play and actively maintained. PixelOne, a multi-tenant restaurant ordering platform built with Kotlin Multiplatform (Android/iOS), a React 19 + TypeScript dashboard, and a Node.js/Firebase backend with Paymob payments.
Core stack: Kotlin, Jetpack Compose, Kotlin Multiplatform (KMP), MVVM, Clean Architecture, Coroutines, Room, Paging 3, DataStore, Koin, REST APIs, Ktor, Firebase (Auth, Firestore, Realtime DB, Functions), Node.js, Play Billing, and Git.
