    Experienced Android Developer with over 3 years of building and launching high-quality mobile apps. With over 33,000 downloads on the Google Play Store. Proficient in Kotlin, Java, and Android Jetpack with a strong focus on MVVM architecture, Room, Firebase, and Retrofit. A fast learner and problem solver, I thrive in collaborative environments, continuously refining my skills to deliver high-performance, scalable applications. I can work on GitHub, Firebase and Android test tools like Espresso and Mockito. Also I learned Android jetpack compose, which is a new framework for building the Android user interface without the need for xml files. Throughout my university studies, I was one of the top students, as I got first place twice on the Software Engineering Department's honor list. I developed an Android app for my graduation project called Fluffy, an app that aims to help take care of cats with daily alerts and notifications about fun facts about cats as well as keeping track of cats' weight. This application relies on some Firebase services such as logging in through a Google account and storing user data. I also developed another app which is a simple tool to dim the screen brightness. This application is available on the Google Play Store in free and pro versions. You will find all the details about my apps in my Portfolio section.
