About Me

I am a person open to learning, who is not afraid to take on any challenge. I believe that my unconditional dedication to everything I do will be the key to success and positive relationships with my co-workers.

Every day

Release Manager.
Automation Test Developer.
Software Developer.
IT Expert.
Father & husband.

I am a person who, under the influence of several decisions, decided to change industries and start developing the programming direction.

So from Gastronomy I went to IT. My goal is to get to know and discover myself, learn and strive for development in the direction of programming. Privately - an "exemplary" husband and father of two children.

In my free time, I guess, like everyone, I like walking, meeting friends, going out to nature, good cinema and I will not refuse good food. In addition, I run two blogs about topics important to me.
