Hi, my name is Anastasia and I am a Scrum-master in Group 107. In 2020, Group 107 came into my life and became my place of strength and development.

I like that company cares about me as a person and about my personal growth. I like being appreciated and listened to. Everytime I feel being motivated and inspired at work.

It is my best decision ever! I like that company combines dynamic business approach with top-notch technologies and very strong people-oriented values.

When I came to work, there were only about 20 of us, at the moment there are 100+ of us, and the feeling of support and friendship remains the same as in a small team.

What I like most is the family atmosphere, interesting projects, flexible management and the opportunity to develop my professional skills every day.

From the beginning, I felt like I’m in a big family where everybody supports each other and ready to help at any time. Group 107 gives great opportunities to develop your skills.
