I had the opportunity to work on the same team that Qing, at the Experian Hitwise. Qing is an excellent professional with a great potential to be exploited. Always willing to assist, share knowledge and participate in a pro-active manner in seeking solutions to problems of day-to-day. Whenever I needed his help, he was ready and willing to provide assistance and knowledge necessary for the moment. Qing was responsible for the physical storage, as well as support for PostgreSQL and MySQL database operations, monitoring and support on-site and off-site for Australia and other countries. A role that in everybody's opinion he performed with confidence and high level of professionalism. I'm sure Qing will be of great value for any team that he should come to work. I hope to have the opportunity to work with him again.
