David Zhang served as a summer intern with the Portland Bureau of Transportation (PBOT) Business Services Group. His supervisor, Andrew Carlstrom, provides a positive evaluation of his work. Zhang performed tasks including researching, collecting, formatting and checking data, scanning records, filing records, and observing a transportation revenue meeting. Carlstrom notes that Zhang was diligent, detail-oriented in organizing data, and had an exemplary work ethic and ability to learn. Carlstrom would highly recommend Zhang for another summer internship with the City.
