Michal R.
Mobile App Developer
Computer Science Master's Graduate, specializing in Mobile Development, focusing strongly on Android. I also have experience with iOS through Kotlin Multiplatform projects. My skills include creating user-friendly UIs with Jetpack Compose and the MVVM architecture. I have extensive experience with camera features, media processing, and integrating AI features into the camera using TensorFlow Lite. Furthermore, I am comfortable integrating REST APIs, handling background tasks, and working with notifications. On the backend, I have built several REST APIs using Java and Spring Boot to support my mobile applications. While not a backend expert, I can handle these tasks when needed and am always eager to learn more. Additionally, I can work with Firebase for backend tasks such as authentication, real-time databases, cloud storage, and push notifications. I also use Firebase Hosting to deploy and manage web apps.
