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.
Responsibilities:

iOS developer, AR Chess

Aug 2018 - Jan 2019
Description: Something simple and fundamental, like classic chess game, gets a real AR boost in this app. Now all chess fans can shift from their regular boards and enjoy the game on the phone. With super cool 3D design, it’s now more realistic than ever. For starters, the functionality is limited to hot-seat game mode, i.e. two players play on 1 device or 1 player conduct a battle with the machine. We decided to leave something from a classic indoor game, at least players can discuss the game in real or beat a computer genius. In the future versions, it will be possible to support multi device mode to play the game by two players remotely on one chess board. Furthermore, chess tournaments, results saving ranking table are in the plan. We’ve used the ARKit in surface recognition (any contrasting horizontal surface can be used for chess board projection). Besides, we’ve taken  into account the main complaints and wishes on the chess app market. Unlike the majority on the  App Store, our app allows:
- taking back moves (if you accidentally drop the piece on the wrong square, now there is an option to correct it)
- automatically turning board around when playing
- repositioning a board during the game.
Responsibilities:

• Work with 3D objects, work with objects in different modes (augmented reality / 3D measurement), built-in purchases, combining the stockfish engine with the application, saving data using RealM
