What I'm looking for

I am looking for a role that values innovation and collaboration, where I can continue to grow and make a meaningful impact.

I am a dedicated Senior Android Engineer with a strong focus on testability, maintainability, readability, and creating products that users find delightful and easy to use. Over the past several years, I have honed my skills at leading companies like Reddit and Dubsmash, where I integrated advanced video creation tools and significantly improved performance based on user feedback.

My experience includes developing innovative features such as advanced video editing, live streaming, and chat functionalities. I embrace a test-driven development (TDD) approach and am passionate about Kotlin and Compose, striving to build intuitive applications that make a real impact. As a member of Toptal, I connect with global clients, ensuring that I deliver reliable and efficient solutions while leading a team of engineers in sprint planning and task management.
