Message

I deliver mobile applications for Oman government and enterprise clients, including GUP, MOCIIP, and Vodafone Oman. For GUP and MOCIIP, I led end-to-end Flutter engineering, from architecture and integrations through production delivery.

At The Weather Channel, I developed Android app features and led the Spotify Promotion Partnership integration. I also worked on subscriptions with RevenueCat and Google Play Billing, and optimized live streaming and video playback.

Across Android engineering roles, I’ve worked on products including BMW infotainment, a SaaS SDK, and digital banking apps. In my side projects, I built EnviroWatch AI for satellite-based emissions monitoring and FlightInvest, an algorithmic trading engine.
