How Russian-speaking analytics estimate their salary rate

There are wide disparities in salary rates among IT specialists. This can be explained by a variety of factors: hard and soft skills of a certain person, their position in the company, location of the said company, etc. We questioned data analytics from Russia and other countries using social networks and then visualized the information obtained in Power BI, which enabled us to discover relevant data and make consequent conclusions.
