I have spent more than four years designing, building and shipping production mobile apps for travel, ride-hailing, e-commerce, healthcare, rental marketplaces and social platforms, for clients in Egypt, Saudi Arabia and Kuwait.

At Techeffic I was the first engineer on the mobile team. I architected a multi-tenant travel platform from an empty repository, and the shared core packages and flavor setup I designed power several white-label apps with more than 200K combined installs. I also led the Flutter team, ran sprint planning and code reviews, and drove the team's move to AI-assisted development.

I like working upstream of the code as well: running requirements workshops, writing user stories and an analysis document, and validating designs against it before development starts. Today I am available full-time and take on project-based work.
