What I'm looking for

I am looking for opportunities that allow me to innovate and grow, preferably in a collaborative environment focused on mobile technology.

As a dedicated mobile developer with over 6 years of experience, I specialize in creating high-performance and user-friendly applications primarily in the fintech and e-commerce sectors. My journey has equipped me with a robust skill set in Java, Kotlin, Flutter, and iOS development, allowing me to tackle diverse challenges and deliver innovative solutions.

Throughout my career, I have successfully managed projects from conception to deployment, ensuring that applications meet both user needs and business objectives. My experience includes working with various teams to enhance existing applications and develop new features, all while maintaining a strong focus on quality and responsiveness. I thrive in collaborative environments and am always eager to learn and adapt to new technologies.
