Passionate about building mobile apps and staying ahead with modern tools

My journey in mobile development began over 5 years ago with a passion for building apps that solve real problems. Starting from Android native with Kotlin, I’ve built and contributed to various mobile applications focused on performance, clean architecture, and great user experience.

Today, I’m advancing my mobile development skills with Flutter and Kotlin Multiplatform, enabling me to deliver high-quality apps for both Android and iOS. I focus on writing maintainable code, collaborating effectively, and staying current with modern tools and best practices.
