I have been in Business Intelligence for 5 years. I enjoy analyzing data assist the business to increase profits by making more informed decisions. This can be done by building a visual dashboard in Qlikview or Power BI, which I have done. I used SQL to import the data. I am very experienced in Qlikview, SQL and excel. I am still relatively a beginner in Power BI, with only a month's experience in Power BI. But Power BI is very similar to Qlikview and actually a bit more easier to use.
