Hi, I’m Mais Assaf, a senior iOS developer and mobile engineer based in Dubai, UAE. I’ve spent 6+ years building native iOS apps and leading cross-functional teams from concept to shipping. My strengths include clean architecture, UI polish, robust REST API integration, and delivering reliable mobile experiences across platforms such as iOS and Flutter. I enjoy turning ideas into beautiful, performant apps that users love. In my recent role, I delivered a production iOS app serving over 1.5 million users, led the migration from native iOS to Flutter to reduce platform-specific duplication by about 35%, and enabled secure payment gateways and push notifications to boost engagement. I’m passionate about code quality, collaboration with product and design, and continuing to learn new technologies to craft delightful user experiences.
