Daily checked the Ratio (spends/deposits) marketing campaigns by different geo, channel, and source. If comparing/channel/geo overcome benchmark I looked for a potential problem and shared my insights with the channel team leader. The marketing department was responsible for the 7 days in product. So I analyze the product. I create reports for company management. Examples: how the sales department works, what is world news, how to be ready for Bitcoin halving, how customers interact with the newsfeed in the apps, create estimations on budgeting, and much more. The main tools that I have used during my career are Power BI, Tableau, Jutiper Notebook, Excel, Azure, and AWS. I have spare time and want to build extra income as a freelancer.
