What I'm looking for

I am looking for a role that fosters innovation and collaboration, where I can leverage my skills in mobile development and contribute to impactful projects.

I am a Senior Android Developer with over 12 years of experience in creating innovative mobile applications. Since 2012, I have honed my skills in Kotlin, Compose, and Kotlin Multiplatform (KMP), allowing me to design and develop robust applications from scratch. My notable achievement includes the development of the Kard app, which has garnered over 100K downloads on the Play Store.

Throughout my freelance career, I have successfully collaborated with global teams to deliver high-quality applications. I take pride in implementing maintainable architectures such as MVVM and Clean Architecture, ensuring that my applications are not only functional but also scalable and easy to maintain. My passion for mobile development drives me to continuously improve my skills and stay updated with the latest technologies.
