JUNIOR FLUTTER / MOBILE DEVELOPER
Profile
Hello! My name is Oleksandr, and I am a Software Developer with a strong background in Android (Kotlin) and a deep focus on the Flutter & Dart ecosystem with over 2 years of commercial experience.
I have practical experience in building and deploying mobile applications, including e-commerce and educational platforms. My expertise lies in creating efficient, high-performance apps with complex UI/UX, custom animations, and robust state management.
On the technical side, I work with Flutter, Dart, and Kotlin. I have a solid understanding of various state management solutions like Provider, BLoC, and Riverpod. I am experienced in architectural patterns such as Clean Architecture and specialized in local data handling using JSON, Drift, and SQL databases. I enjoy diving "under the hood" of the framework to ensure smooth performance and scalable code.
