        Alexey is a highly competent ETL architect and system engineer.  He is methodical in troubleshooting and excels in database tuning.  Report response times went from minutes to several seconds. Alexey does an excellent job of explaining his findings on data discrepancies to the users in a clear cut and concise manner.  I've worked with Alexey on a very time-challenged data warehouse conversion project.  During this time, I was impressed by his intelligence, team player attitude and his willingness to accept whatever tasks were assigned to him.  His knowledge of the existing Oracle data warehouse and its ETL was a contributing factor to the successful conversion.   I wish him the best in all his current and future endeavors.

        Alexey is one of the most talented Data warehouse professional I've 
ever worked with. His profound knowledge on data warehouse and ETL played a key role in our organization. He developed comprehensive logic to help business analyzing data, help doing planning and forecasting. 
During our EDW Netezza conversion project, he re-designed several major data warehouse areas, improving the performance significantly, and provided more accurate data with less effort. 
I can recommend Alexey as a positive asset to any organization.
