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. Here I found the best mentors who teach me every day and help me to develop as a professional. Here I found a cool team that became friends and even family for me. I love how the company grows, welcomes new employees every day. I also adore the responsibility of each and the friendly relations within the team. I want our Group 107 family to only develop and grow.

I have been working for Group 107 for almost 1.5 years.When I came to work there were only about 20 people, at the moment there are more than 100 of us and the feeling of support and friendship remains the same as in a small team. I love our people, I love the pace of the company, I love the fact that we are always moving forward. In short, our Group 107 is a big Italian family!
