For all women who are thinking about developing a career in IT, I would like to share my experience. My name is Natalia Burlakova, I currently hold the position of Senior Security Solutions specialist at Microsoft Central Europe, and this year will be the thirteenth year that I have been developing my career in a company that started with an office in Ukraine, and now at the level of European countries. I came to the company from the areas of marketing and sales to the position of a specialist in workplace solutions in the marketing team. I was very lucky, it was a time when cloud solutions were just entering the market. Few people knew what it was, so I learned along with the industry. Then I was more involved in sales, worked with large companies, with teams that solved technical problems for clients, and constantly learned. And today I already work in the technical direction, namely cybersecurity.
