What I'm looking for

I’m looking for a team where I can build useful, high-quality mobile apps with modern Kotlin and Jetpack. I want ownership from idea to release, strong collaboration, and opportunities to keep improving performance while mentoring others.

I’m a Senior Android Developer who loves building useful, high-quality mobile apps—taking ideas from start to release. I work with modern tools like Kotlin, Jetpack Compose, MVVM, MVI, and clean code, and I enjoy solving problems that make apps faster and more reliable.

At My Cash (Nasr City, Egypt), I mentor and guide junior/Mid-level developers through code reviews and support their growth. I also manage and drive app releases across Google Play, POS Stores, and Huawei Store, collaborating closely with stakeholders to design and launch new features.

I’m proud of results like reducing bugs and crashes by 70% and refactoring large parts of the codebase for improved stability and performance. I’ve worked to keep delivery smooth through strong release management and clear coordination with product and engineering teams.

Earlier roles strengthened my breadth across app development and delivery: from building quality applications and managing Google Play publications at Almajd Academy and Ayamdica, to implementing user stories and maintaining apps at Visions-Tech. I’m always ready to learn and work with teams to build great products.
