About Me

I'm a Senior Android Developer based in Egypt, currently working with Vodafone Egypt on large-scale product experiences used by millions. My work sits at the intersection of modern Android engineering, payment reliability, and performance-driven mobile product delivery.

Across Vodafone, e-finance, Mtor, and ProLive, I've built Android apps from scratch, led feature revamps, integrated secure payment gateways, built POS and KIOSK printing modules, and mentored Android interns into stronger production contributors.
