Senior Android engineer specializing in Kotlin, Jetpack Compose, and scalable mobile architectures.
I am a Senior Android Engineer with over 10 years of experience building and deploying enterprise and consumer Android applications. I specialize in Kotlin and Java, Jetpack Compose, RESTful APIs, performance tuning, and end-to-end mobile delivery.
I've contributed to large-scale codebases at major companies, built automated refactoring tools, and designed optimized on-device storage using SQLite and Room. I prioritize testing (TDD, unit, integration) and reliable CI/CD pipelines to maintain high code quality.
I have full-stack experience building backend services with Java Spring Boot and integrating complex third-party services including authentication and mapping APIs. I routinely lead code reviews, recommend architecture and scalability improvements, and resolve production issues using observability tools.
I hold an MBA in Computer Science and an MS in Computer Science, and I thrive in fast-paced team environments or when working independently to scope and deliver high-impact features.
