About myself

The passionate dedicated person who understood that life is a continuous journey of acquiring new
knowledge.

I started to learn, new to me, frontiers of logistics at university and achieved some excellent results in getting a
job at a foreign company.

Through this experience, I gained some valuable skills like communicating with foreign companies and
arranging that the work will be done in time without any delay.

After graduating from University I left the job to let me improve my skills in programming and making projects
in Unity.

Bullet Storm
In the test project, where the player moves and shoots enemies. Objective: get the high score

Flappy Bird
The project was given by the company to test skills in C# and Unity. By the task, I can't use additional plugins, so I
tried to use the Service locator, to resolve dependency injection. A service locator is a component/class that
encapsulates knowledge of how to obtain services that the Client needs/depends upon. It is a single point of contact
for the Client to get services. It is a singleton registry for all services that are used by the client. Another task was to
create a .json file to store high scores for each level and volume sound even after the quiting app. To solve this I
create SaveService.

Grocery Idle

collect fruits by tapping on them, the character grabs the fruit and moves his hand with it to the basket. Objective:
collect fruits by task
