At Optimiza, I built KooraKings’ native Android app in Kotlin, then migrated the sports prediction platform to Flutter while sustaining 100,000+ concurrent live connections during major matches. I also delivered prediction contests with chat and live leaderboards in Arabic and English.
At Optimiza, I built Marham healthcare features for doctor search, appointment booking, and health records; booking success rose 30%. I also built Swabee in Flutter, supporting 10,000+ completed swaps.
As an independent Flutter developer, I built three client apps: a white-label loyalty app, an HR attendance app with geofenced check-in, and a delivery app with continuous driver tracking. All three are complete and pending client launch.
Earlier, I refactored an e-commerce app at Catchyz Holding Ltd., improving performance by 20% and cutting crash rates by 40%. I’ve also developed Android and React Native apps, maintained Linux servers, and mentored a junior developer in Flutter and Dart.
