Worked together with eBay security/data analysis teams to create cross-system feature data collection and engineering across hundreds of database schemas for the continuous ongoing models training and risk detection. I utilized internally developed technology (scripts) and Princeton Softech (IBM Infosphere Optim) for feature data extraction, engineering, and incremental training of the machine learning models. I have led eBay’s tuning and capacity planning for a new Teradata environment using Bez and internal Teradata tools. I have participated in evaluating and selecting the 3rd party capacity planning and machine learning vendors.Supervised DBA’s technical development (team of 25); conducted interviewing, training, and certification activities for the Database technologies group.
