Confidential is a healthcare Recoveries company which has its own application called Troveris which is used by the Recovery agents to view the claims and lien and make recoveries. Hundreds of files are received everyday from various clients which needed to be loaded into the application based on business rules.

Through this application, the end users can submit a request to fetch Claims based on certain criteria and the ‘History Request/Return’ process picks up the request and runs ETL programs, Stored procedures and returns the data that was requested back to the application based the criteria that they submitted.

Position: ETL Developer

The Marketing Support Replatforming project will consolidate data, process deals in an automated fashion and reduce the overall time it takes to generate a payment after quarter end. Currently this is a legacy system on the mainframe with little flexibility for changing deals. In addition, there is a large amount of manual calculation and validation required to generate payments at quarter end which delays the payments to dealers. The new system will run off a "Mid-Tier" data warehouse and allow for more flexibility in deal parameters and input. The automation of the payment calculations will reduce processing time.
