I lead a geographically disbursed team that maintains the content for a highly trafficked real time web site serving up both real time and historical data and statistics on the nation’s water resources. I was the system manager for the USGS Water Data for the Nation Web Site and the USGS Water Services Web Site. I directed and supervised a team of five full time and direct four part time employees in the operation and development of a highly trafficked and critical real-time web site. The site is used by the USGS to deliver and showcase its voluminous water science data and is the primary portal for its water science data. Traffic on the sites are approximately 30 million page requests per month and have grown about six fold during my employment at the USGS. My work has involved aggressive steps to improve the performance and functionality of the site to a new higher performing platform. In addition, I was the champion and advocate for water web services for the USGS, resulting in a new highly efficient platform for the delivery of water science data using XML, JSON and other technologies. USGS Water Services web site averages about 10 million page requests per month. Together the two sites I managed ranked #1 and #3 most trafficked sites within the USGS National Web System when I left the job. I also advocated and oversaw the use of virtual server technologies, which were adapted and have saved the government many thousands of dollars. My work has been widely recognized and has included two Exceptional performance awards.
