Professional Experience
Med-Assets, Plano, TX
Software SystemEngineer (Dec 2008 – Now): Worked on new features and maintained the core product called
XCLAIM, a revenue cycle management software used by hospitals to keep track their billing cycle, using Agile and
SCRUM methodology. This software is client-server application, based on .NET technology with n-Tier
Architecture.
Responsibilities:
 Involved in new releasesof the software by planning iterationsand completingassigneduser stories.
 Involved in all phases of SDLC including requirements gathering, design, development, unit testing, deployment,
post production support and documentation.
 Experienced in components on client side: updating the main menu to add new items, creating new web forms for
these new items with Developer Express software, modifying Claim Editor (an Active X component written in
C++ used to validate claim against payer rules on the client side) with new features.
 Experienced handling user events on the server side: updating data access layer with new methods relatingto views,
tables, store procedures, ADO.NET, mapping XML data into business object.
 Integrated other products to XCLAIM by calling XML web services to retrieve the data and used XSLT to
transform it to match business objects.
 Created auto code generation tool to create C# classes to wrap claim XML data instead of using XML paths.
 Updated auto import service (a window service to pick up data files that clients drop in SFTP server to import
them into XCLAIM system) to handle new format data files.
 Created reporting services that our client can subscribe and set up schedules to run.
 Set up new servers (web server, task server) for production and test environments as needed to handle more
hospitals.

Software Custom Engineer (Dec 2006 – Nov 2008): Worked on custom applications for a specific hospital. In
addition to using the core product XCLAIM, the hospitals have demands to customize their data. Mainly, set up
new sites for new hospitals by implementing custom applications in C#, using stored procedures, XML and
common base classes (DAL) to retrieve and manipulate the data.
Responsibilities:
 Set up resources (task server, web server, database server)for new site.
 Set up and tested custom data mapping including insurance and physician master files.
 Involved in multiple core products (XCLAIM, XDM, XDIRECT, ABN, CCA)
 Implemented and tested custom routines to update data sent in by clients.
