• 6+ years of professional software engineering experience, including significant experience building Android applications at scale.
• Deep expertise in Kotlin and modern Android development.
• Strong understanding of Android architecture, application lifecycle, concurrency, networking, and performance optimization.
• Strong product intuition and a passion for creating exceptional user experiences.
