Senior Mobile Developer
Android developer

Within 4 years I'm involved in Android development. One of my main skills is to create professional, responsive, intuitive mobile applications for Android.

I know how to create quality android apps. I am responsible and always in touch with my clients. These stories when a freelancer hasn't communicated with a customer for several days are not about me. Also, I complete tasks on time because I understand that it is important for you.

I am a responsible worker. I do my work with the full dedication and strive for excellent quality. From my side, I guarantee high-quality work while doing it as fast as possible. I am available to start work immediately and up to 40 hours per week.

Technical Skill Set:

  • Good understanding of Core Java, Kotlin concepts (oops, collections and multithreading)
  • Experience working with different versions of Android, and how to deal with different screen sizes
  • Familiarity with RESTful APIs to connect Android applications to back-end services (Retrofit, OkHttp, Websockets)
  • Experience with offline database storage (Sqlite, Realm)
  • Knowledge of the open-source Android ecosystem and the libraries available for common tasks. Android SDK (Fragment API, Bluetooth/BLE API, Camera API, Service API, BroadcastReceiver, Job Scheduler API)
  • Android Testing (Robolectric, Mockito, Espresso, UI Automator, Junit, Hamcrest)
  • Image processing (Picasso, Glide, Fresco)
  • Google Play Services (Maps/Places, Location, GCM, AdMob/DFP, Drive, Face Detection)
  • Firebase (Auth, Database, Notifications, Analytics, Cloud Functions, Crash Reporting etc.)
  • Social networks (Facebook SDK, Twitter SDK, Instagram SDK, Vkontakte SDK)
  • Proficient understanding of code versioning tools, such as Git
  • Strong knowledge of Android UI design principles, patterns, and best practices (Support libraries, Custom views, Custom themes/styles)

Looking forward to work with you!
