Can you tell about the most significant projects or tasks you have implemented recently?

Recently, I have been working on several projects:

• Developing a mobile e-commerce application for Android using MVVM architecture and Jetpack components. This included integration with REST API, offline caching, and push notifications.

• Creating a chat feature using WebSocket for real-time message exchange.

• Optimizing application performance: profiling, reducing startup time, and optimizing database operations with Room.

• Implementing a responsive UI supporting different screen sizes and dark theme.

These tasks have helped improve user experience and increase the stability of the application.
