Abd User

I am a Senior Mobile Application Developer with five years of hands-on experience building high-performance cross-platform apps using React Native, Expo, and TypeScript. I focus on speed, reliability, and maintainable code to deliver measurable product improvements.

My work includes integrating REST and GraphQL APIs, implementing state management with Redux and MobX, and leveraging Firebase and cloud services for realtime features and notifications. I have a strong track record of reducing load times, increasing user engagement, and boosting retention through targeted performance and UX improvements.

I collaborate closely with backend and product teams during agile sprints, mentor junior developers, and contribute to CI/CD pipelines and automated testing to improve release velocity and stability. Notable achievements include improving app search speed, raising daily interactions, and scaling apps to handle significantly more users.

I bring a pragmatic, data-informed approach to mobile engineering, emphasizing debugging, refactoring, and delivering polished user experiences that align with business goals.
