Senior iOS Engineer @ Gathern Holding · ex-CAFU, Vodafone
Co-founder, SwiftCairo · Creator, SalahBreak
8+ years turning ambitious product ideas into iOS apps that ship to millions of users, across three regions (MENA, Europe & LATAM).
I help product teams ship iOS apps that are fast, reliable, and loved by users, wherever in the world they live. I've led iOS engineering at a hospitality unicorn in KSA (Gathern), the Middle East's largest fuel-delivery platform (CAFU), a multinational telco operating across Europe (Vodafone), and a Budapest-based product agency serving LATAM clients. On the side, I co-founded SwiftCairo, Egypt's largest iOS community, and lead the iOS team at Ameen, building faith-tech that serves Muslims worldwide.
I care equally about the product, the people building it, and the code underneath.
"iOS engineer and educator. Builds scalable mobile experiences used by millions throughout the Middle East and North Africa. Co-founder of SwiftCairo, one of the region's most active iOS communities, leading through events, webinars, and technical sessions, and creating educational content to make high-quality iOS development knowledge more widely accessible."

Technology that serves Muslims worldwide is a personal mission, not a side gig. I lead the iOS team at Ameen, a comprehensive Islamic lifestyle app combining Quran, prayer times, dhikr, Zakat & Islamic finance, and broader spiritual tools in one place.
📱 Ameen · Lead iOS Engineer
🌙 Reached 2M+ users during Ramadan. Peak-traffic scale meets spiritually meaningful UX. Built with the same engineering rigor I bring to commercial products: clean architecture, modular SPM, privacy-first analytics, and respectful, low-distraction UX.

🕌 SalahBreak · Creator & MaintainerMy own prayer-companion app spanning the entire Apple ecosystem: iPhone, iPad, Apple Watch, macOS, CarPlay, and Home Screen widgets. Built solo as a labor of love, partly to push myself across every Apple platform, and partly to give the community something thoughtful and free.
🤲 More Islamic-tech experiments in the works. DM me if you're building in this space. |
Building for the Ummah is the work I'm proudest of. If you're building a product that serves Muslims and you care about doing it right, let's talk.
