Data Analyst · SQL Developer · ETL Developer · Data Specialist · Data Scientist
Mid-level (2-4 years experience)
For nine years I worked for AC nielsen. My main responsibilities were ETL (extract, transform, load), loading sales data into local data warehouse. I got sales data from different retailers (LT, BY) in different formats. I created scripts what transformed all that data. I mostly used SQL (MS foxpro) and MS Excel. Additionally I had to make data analysis, create reports and other manipuliations with data.
