    I have over 4 years of experience in mobile application programming. I began my professional journey by learning Java and Kotlin and developing applications using Android Studio. Along the way, I gained valuable experiences that contributed to my personal and professional growth and paved the way for my entry into the world of Flutter. To date, I have implemented numerous projects on both platforms, some of which have been successfully launched. These experiences motivated me to develop an interest in backend development as well, and I started working with JavaScript and the Express framework. I'm passionate about solving complex problems and always take enthusiastic steps on the path of learning and growth.
