PROFESSIONAL EXPERIENCE


Confidential, Minneapolis, MN
(PLSQL) Developer May 2012- Till now

Consumer Pricing Initiate (CPI) has several work streams. Confidential, is one of the top 1000 sites in the world and is in the Retailers category. The primary objectives of the Data work stream are to create one common version of Quote and Policy data for Auto. Today in PL (Personal Lines) Applications, policy and quote data reside in multiple data marts, making itdifficult to analyze performance without significant manual intervention to pull all of the data, even prior to analysis. This project is a great example of Operational Excellence, as it takes the basic quote data 'manufacturing' process out of the hands of Marketing and other functions, and creates an automated and centralized source for the quote data. Creating this common source for quote data meansthat leveraging the same data resulting in much more consistency around respective analytic processes and reporting. Additionally, this project willalso result in common definitions of the various data points (ie : responses, quotes, conversions, issues) which will continue to support consistency across functions. In addition to these operational efficiencies, this new data source will include attributes that marketing have not previously had access to, therebyallowing for potentially greater analysis opportunities to understand various program results.
