What I'm looking for

I am looking for opportunities that foster innovation, collaboration, and professional growth.

As a Senior Android Developer with over 13 years of experience, I have honed my skills in designing high-performance Android applications. My expertise in Android SDK, Kotlin, and Java enables me to create efficient and user-friendly software solutions. I take pride in my ability to optimize code and enhance UI/UX, which has significantly contributed to project success and client satisfaction.

Throughout my career, I have worked with various companies, including M&I Systems and Darwin Digital, where I was responsible for software design, development, and bug fixing. My experience includes integrating devices with barcode scanners, implementing AI in Android apps, and refactoring legacy code to keep up with technological advancements. I have also taken on leadership roles, mentoring junior developers and managing resources effectively.

I am passionate about continuous learning and staying updated with the latest trends in Android development. My goal is to leverage my extensive experience to contribute to innovative projects that enhance user experiences and drive business success.
