About Me

I'm a flexible and results-driven Senior Android Engineer with over 6 years of experience in designing, developing, and optimizing high-performance mobile applications. My passion lies in delivering seamless user experiences and building scalable, secure applications.

Throughout my career, I've led the development of complex Android applications, including a GDPR-compliant telehealth and well-being application (eDoktor) involving secure video consultations, and contributed significantly to a major eCommerce platform (Dhamaka Shopping) with a focus on real-time data and payment gateway integrations. I've also worked on SDKs for financial services (shurjoPay) and Learning Management Systems (Retina LMS).

I possess expertise in the Android SDK, Android Architecture Components, Kotlin, and Jetpack Compose. My architectural approach leans towards MVVM, Clean Architecture, and Modular Design, always adhering to SOLID Principles. I'm proficient with a wide array of libraries and tools, including REST, Retrofit, LiveData, Flow, Kotlin Coroutines, Room, Realm, GraphQL, WebSocket, Dagger, Hilt, WorkManager, and Firebase.

Beyond development, I'm a regular participant in online competitive programming competitions and have actively participated in several onsite national and international programming contests, honing my problem-solving skills and understanding of Data Structures & Algorithms. I thrive in agile environments, embracing Scrum methodologies and the collaborative spirit of pair programming.

I am dedicated to continuous learning and eager to leverage my skills to create innovative and impactful mobile solutions.
