What I'm looking for

I seek roles where I can architect scalable Android apps, drive performance and CI/CD improvements, collaborate cross-functionally, and grow toward technical leadership in a product-focused team.

I am a results-driven Android developer with deep expertise in Kotlin, Jetpack Compose, MVVM/MVI, and Clean Architecture, focused on building production-grade, scalable, and user-focused mobile applications. I have driven measurable improvements in performance and delivery through architecture modernization, networking optimizations, and CI/CD automation.

At ElGrocer and Ozi Technology I resolved scaling and performance challenges, migrated legacy async frameworks to coroutines, and implemented observability and deployment pipelines that improved API response times and reduced release cycles. I prioritize clean, testable code, SOLID principles, and cross-functional collaboration to align engineering with product and design goals.
