Most of my career has been spent in mobile development for Android. The first version of Android I started working with was 2.1. I had the opportunity to trace the entire evolution of the OS from a programmer's perspective, starting from the times when AsyncTask seemed like a good idea, and real-time image processing required writing code using the NDK, to the advent of Compose and Kotlin Multiplatform. It would be correct to say that I have worked with all the paradigms that have ever been widely used for Android.
I have tackled a very broad spectrum of tasks, from complex algorithmic problems, apps with sophisticated client-side data processing, to "layout development", high-load multithreaded applications, and of course, animations, animations, and a bit more animations. My experience includes designing architecture from scratch as well as gradually integrating new architecture into very large projects along with writing features. Also covered the entire spectrum of code testing approaches, from projects without any testing to those that applied a comprehensive range of tests (unit, integration, hermetic, and even units for Activities & Fragments). And, of course, there was a lot of code review.
I have extensive experience working with teams of 1 to 50+ members, both remotely and in-office, in product and outsourcing settings.
Programming Languages: Java, Kotlin, Dart, C++
Technologies and libraries: Android SDK, Flutter SDK, Material Design 3, widgets, JSON, SQL, REST, Gradle, MVP, MVVM, Retrofit, RxJava, Mockito, Robolectric, Espresso, Dagger 2, Data binding, Clean architecture, RxJava, Dagger/Hilt. Understanding of OOP principles, knowledge of design patterns, data structures, multithreading and synchronization principles, SQLite and ORM, performance and memory optimization skills, big experience in developing client-server applications, code review and quality analysis, UI animations, data transfer protocols, knowledge of json and xml formats, knowledges in image recognition methods, extensive knowledge in data compression.
- My first experience in non-commercial programming involved developing data compression algorithms and their implementation. At the beginning of my professional career in a department specializing in image recognition, I was charged with developing a proprietary barcode format and to be able to recognize and encode data in it (at that time, QR codes were not yet represented on mobile devices).
- GrubHub project, which adhered to extremely high standards of code quality and control including tests of all types, stringent coding standards and very detailed code review processes.
- Some of my own projects that I am currently working on. Without disclosing the details of the projects, I can say that a special emphasis was placed on design and a convenient, consistent interface. This required a very detailed study of the subject area and analysis of the last two versions of Material Design.

Mainly I worked with Java and have slight production experience with Kotlin. At work, I regularly used Git and had some tasks where I used Retrofit, OkHttp, Glide, Dagger 2, JUnit, Mockito, PowerMock, and Firebase Cloud Messaging. Usually, I worked with Gerrit and GitHub, and I have little experience with Gitlab.
My plan for the near future is to become a Middle Android Developer with strong Kotlin knowledge and rich technical experience.
