Freelancer profile translated to English.

Description

Senior Android Engineer with over 15 years of experience, I work as a freelancer on the design, development, and optimization of complex mobile applications.

I support my clients throughout the entire product cycle: architecture, development, performance, UX, and publication.

I master the modern Android ecosystem: Kotlin, Jetpack Compose, Coroutines, Flow, Hilt, Room, Protobuf, Firebase, Clean Architecture, and MVVM.

My approach is based on clear, testable, and durable code, always oriented towards the product and the user.

I have contributed to large-scale projects for TAG Heuer (Wear OS, UI offload, sports sensors) and designed consumer applications with hundreds of thousands of downloads.

As a recognized trainer, I have also shared my Android and Kotlin knowledge with technical teams and training organizations.

My goal: to deliver elegant, robust, and durable applications, combining performance and quality of experience.
