Description: The application is a link between the Philips devices installed on the truck and the display of data from these devices on the driver's phone. The application allows, if driver has the necessary devices, to monitor the status of tire pressure, doors sensors and windows sensors, etc. It all depends on the set of devices that a particular truck has. A special gateway allows to pair devices with the application via bluetooth.The application also monitors and rewards the driver for installing new devices or for safe driving, such as braking intensity, travel time, safe speed, etc., and gives the driver various rewards in the form of badges.The application also has a social component. So registered users can communicate via a call (both a regular call and a CB radio) with other users. The user can set different statuses depending on how free to call.Inside there are several shops where driver can buy new devices or merch.

Lead Android developer

Sept 2020 - May 2021
Description: An application for manage bank transactions, and control balance. An important part of this project was that you need to use both the new API and the old one, and i have needed to create abstract data models and mappers that would bring data from API to abstract models, there were also several custom views that we build from scratch to make app more beautiful. Also it was necessary to encode all the data, because it’s a banking application.
Responsibilities:

• Researching effective technical solutions, developing features for android, prioritizing tasks and features

Technologies: Kotlin, Realm, Gradle, Firebase, MVVM, DataBinding, Navigation Architecture Component, Clean Architecture, Coroutines, Retrofit, Dagger 2, Jackson, AppCenter.

Sept 2018 - Dec 2019
Description: An application for manage your tasks and do it as simple as it could be like messaging. I developed the app from scratch for android platform using clean architecture coupled with MVP approach. For MVP approach, we used Moxy library that help us work with MVP easier. Storage side must be very quickly and maintainable, so for DB realization we used Realm as this powerful library do CRUD operations very fast and reduces the amount of code at times in comparison with other libraries. To communicate with server we used Volley library as it support Automatic scheduling of network requests, Multiple concurrent network connections. In addition, support for request prioritization. For communication, we used Json and GSON library for it. The benefit we get with GSON is that object mapping can save the time spent writing code. Also I fix bugs and perform testing, besides this I optimize app in every way, to increase performance. The team's communication mode was based on Agile(Scrum) methodology and Jira service for accurate time tracking. In addition, we integrated Firebase with Crashlytic to authentication, notification and track issues.
Responsibilities:

• Developing new functionality (UI changes, microservice functionality, database stored procedures).
• Testing of own features, documenting test plans.
• General maintenance bug fixes.

Description: Mobile application for browsing colorful HD wallpapers, cropping and setting wallpapers from huge database. The desktop and the lock screen are what you see every time you pick up the phone, right? My goal is to make each use of the phone more enjoyable, because it is more pleasant to use the phone when the wallpaper is a beautiful HD picture with resolution up to 8k that you have chosen. I wanted to do fast app with simple interface, custom comfortable filters, with robust code and I think I successfully do it. I developed the app with use MVVM approach coupled with DataBinding. All it written in Kotlin language. For communication with API I use Retrofit and OkHttp. In addition, I used Crashlytic for catching bugs. All this technology help me to do this app fast and maintainable.

Dec 2016 - Jul 2017
Description: Platform with interesting facts and embedded advertising for monetization. Since it was supposed to have subcategories, it was decided to make a side menu to switch between them. For a more convenient menu management, it was decided to use the MaterialDrawer library. OkHttp was used to synchronize with the server because the news parser and fact manager were located remotely. Also was used MVVM approach. The application was made from scratch and was followed up to the fill on Google Play.
Responsibilities:

• Development from scratch

Technologies: Java, Kotlin, Gradle, Firebase, Kotlin extensions, MVVM, Data Binding, OkHttp, Butterknife, MaterialDrawer, GreenDAO, Glide, Crashlytics.
