August 2010 – 2/2011 SSRS Report Writer/Database Developer – Productive Data Solutions, Tempe, AZ

I was initially hired as a Contractor to develop SSRS reports for Healthways Inc. I did such a good job completing more than 60 reports ahead of schedule that Healthways, decided to use me on their other database projects. One such project utilized SQL 2008 R2 with Service Broker and XML messages. I was responsible for the development of nearly all of the Stored Procedures, Functions, Tables, Views, and XML based Service Broker messages. In the short time that I have been at Healthways I have made a significant contribution to three of their projects and utilized my .Net skills to write an RS deployment script that deployed reports to a distributed folder structure.
