Performance Optimization and Clean Architecture
Mobile apps should feel fast and behave predictably. I optimize code and app behavior by improving memory usage, reducing unnecessary work on the main thread, and refining data flow between UI and backend services. I also structure projects using SOLID principles and dependency injection so your app remains easy to extend and maintain.

Firebase and API Integration That Actually Works
Many students face issues when connecting mobile apps with backend services. I help you implement Firebase and REST API integration in a reliable way, so authentication, data retrieval, and updates behave correctly. You get solutions that handle errors properly, manage loading states, and keep the UI responsive.
