As an Android developer with over 8 years of experience, including 3 years as a freelance, I have had the privilege of working with a wide variety of companies, teams, and methodologies. My expertise lies in Android development, particularly in Kotlin, including Compose, Multiplatform, and various Kotlin-related libraries. I thrive in dynamic environments, having successfully delivered projects across different tech stacks and collaborated with teams using Agile and other development approaches. In addition to development, I’ve helped companies recruit new developers, ensuring they build strong, effective teams. I am passionate about testing and continuous integration/continuous deployment (CI/CD), which I believe are key to delivering high-quality software. While I am proficient in Java, my focus is now exclusively on Kotlin, leveraging its modern features and capabilities to build robust, scalable mobile applications.
