About me

Programing has been my hobby since i remember. I like researching new topics and technologies which makes my R&D role perfect suitable for me. Machine Learning and AI topics are most interesting to me.

I like games, both playing and developing them. One of my main hobbies and interests is Unity. But I am always ready and happy to learn new languages and environments.

The tools we use

The main tool our team uses is Unity. We have a deep knowledge of that engine.

Tools such as Jira, Everhour and Shortcut are used to manage projects well.
Git, SourceTree and Plastic are our preferred choice for version control.

To communicate with clients we usually use Slack, Discord, Microsoft Teams, Google Meet and occasionally Skype.
