Work History
Software Engineer IV
Emdeon Pharmacy Services
Asheville, NC
11.2008 - Current
- Recently began POC work converting data access and ETL processes to .Net Core apps running as Azure Container apps.
- Undertook an initiative to move legacy claim processing initially to AWS cloud, but now the current focus is migration to Azure while re-architecting to microservices with DevOps pipelines.
- Took dev ownership of our stable of ASP.Net applications. In charge of bug fixes, updates, and modifications to data-driven web tools. They use C# code-behind and the DevExpress control package.
- Designed and coded a process logging framework built on MSMQ and MSSQL that is populated by our applications.
- Maintain and extend the current base of production claims processing software. This is a body of Linux C code for claims switching, editing, and adjudication. We are currently migrating this functionality to Windows C# .NET and MSSQL.
- Redesigned the workflow of the EDI department using a set of new C# applications and PowerShell scripts to automate nearly the entire process for adjudicating and reconciling claims handled in X12 transactions.
- Created a new service that parses and stores payer and file-level disposition data sent to us by our parent company (Emdeon) as we migrate the sending of claims through them for adjudication. This is a multi-threaded server application that currently parses and stores data for ~350k claims per day. Entity Framework mapping to MSSQL is used for the DB backend.
- Created a new system for transforming customer MSSQL claim data into ANSI X12 transactions. These are sent to Medicare and various Medicaid’s for adjudication and eventual payment. When the adjudication response X12’s come back, another set of applications parses the X12 and reconciles the payment data against what we sent. This system was done with C# Winforms apps using ADO.NET and Entity Framework. Custom objects were written for parsing/creating X12 data and rules processing.
- Designed and developed a service for accepting vaccination claim data and transforming it into HL7 and shipping it to a web service clearinghouse for CDC tracking.
