ABOUT ME
Senior data visualization expert with 6+ years experience in Qlikview, Tableau, and SQL.
Senior data visualization expert with 6+ years experience in Qlikview, Tableau, and SQL.
I have been working since 2014 as a data visualization expert. Graduated from one of the top universities and worked for the top companies in my country. Also, some of them are known globally like PepsiCo, Coca Cola.
I have been working with Qlikview since the beginning of my career. In parallel to Qlikview, I am also using SQL as a query language to get my data to manipulate in my visualization tools. I also have expertise in Tableau. I have done Qlikview to Tableau migration project by myself in a very big company. I mentored/taught 3 junior data experts in my career.

I am highly skilled with the script side of it. Not only I can write Qlikview's own query language effectively but also can use some programming techniques like loops, variables, etc. I can help you write very complex formulas including Set Analysis or variables with parameters on the front side. I have strong visualization expertise that I can create some graphs that is not exist in Qlikview natively. I can help you create PDF reports that can be scheduled. I also have server side expertise that I can help your QMC problems.
