Hi,
I am an ETL / Data warehousing developer with 4.5 years of industry experience. I have experience in different databases like mssql,oracle & netezza. As a Dwbi developer, I am doing data analysis, modeling and performance optimization activities, and as you know, since it is Data warehouse, I am dealing with large amount of data. So I believe I can analyze data and built queries for you. Kindly let me know your detailed requirement so that I can come up with a plan.
