Lead Android Engineer with 7+ years of experience building mobile apps used by millions of people worldwide.
I currently lead Android development for P&G’s Pampers Club rewards app across multiple countries in Europe, North America, Asia and the Middle East. There I drove a full Jetpack Compose migration, a platform-wide design system revamp, a 40% reduction in API calls and a 99.8% crash-free rate. I’ve also launched the app in new markets including India, Austria, Canada and Switzerland.
Over my career I’ve built a wide range of products:
• Biometric authentication systems (voice, face, fingerprint and behavioral)
• Banking apps (Bank of Jordan)
• Government e-services (Pakistan Online E-Visa)
• Video and social platforms, conferencing apps and secure VPN apps
• Travel, fitness and loyalty/rewards apps
What I do:
• Native Android: Kotlin, Java, Jetpack Compose, MVVM/MVI, Clean Architecture
• Cross-platform: Flutter & Dart for Android and iOS
• AI & ML: LLM integrations, RAG assistants and recommendation systems (MS in Data Science, FAST-NUCES)
• Backend & DevOps: FastAPI, Firebase, REST APIs, Docker, CI/CD, Azure DevOps
• Quality: unit testing (JUnit, Mockito, MockK), SonarQube, code reviews, performance tuning
Why work with me:
I’ve led teams, mentored developers and delivered for global enterprise clients, so I know how to ship reliable, scalable apps on time. I communicate clearly, take full ownership, and write code that’s easy to maintain long after delivery.
Available for freelance projects and long-term contracts, with flexible hours to work with clients in any time zone worldwide. Let’s build something great together.
Developed features for the Bank of Jordan’s mobile banking app, turning wireframes into production screens and integrating core banking services and middleware, with reusable components for faster delivery.
Built an authentication SDK and app that secures logins with multiple biometric models: voiceprint, faceprint, fingerprint and swipe-behavior analysis. Developed the reusable library, new features each sprint, and major refactoring for performance and reliability.
