Chapel Hill, Nc

Developed applications and APIs as member of Agile integrations team responsible for interfacing with third party systems. Technologies included Windows console applications, WCF and REST Web APIs, SQL Server, and cloud-based platforms in AWS and Azure. Applications written primarily in C# (.NET 4 through .NET Core) and Angular.• Implemented microservice-based process flow system written in C# and .NET 5 (.NET Core) hosted in Azure. The microservices retrieved data from FTP and REST endpoints and transformed that data. Communications between microservices were achieved by publishing and subscribing to events in Apache Kafka.• Wrote and maintained truck and trailer repair application in Angular styled with Bootstrap. This application allowed data entry by users and integrated with third party vendors via REST APIs to pull repair data from their systems for the same vehicle and seamlessly displayed data from both systems.• Designed architecture and wrote AWS Lambda functions in Python as part of a Cloud platform which consisted of a suite of external REST endpoints exposed through API Gateway. The Lambda functions in turn accessed data in MongoDB database or called internal REST endpoints.• Led project that integrated with third party API, storing information in the cloud within MongoDB, with REST endpoints exposed through Flask/Python as well as Angular frontend. Responsibilities included being primary interface to customer, researching the API, designing the architecture, and writing Jiras from business and technical requirements, while being fulltime developer on the project.• Wrote and maintained C# and VB.NET applications that retrieved odometer, fault code and GPS location data from in-cab truck devices via telematics and wrote this data to the database directly or through web services. Reduced defect level by an estimated 80% in first nine months.• Wrote detailed design and user-level documentation, including UML sequence and state diagrams.

Cary, Nc

Created web and desktop .NET applications in C# and VB.NET with SQL Server storage in support of Medicaid medical review contracts, spanning the range of prospective, concurrent and retrospective review types. This required a strong knowledge of NC Medicaid eligibility and claims record structures.• Created and maintained applications for Medicaid reviews. Generally each application was a greenfield project of 1-2 developers storing and retrieving data specific to that contract. Modeled database schemas, created tables and stored procedures, implemented applications in WPF, Windows Forms and ASP.NET. Involved in all phases of development, from requirements gathering through customer support (including writing ad hoc SQL queries).• Wrote retrospective review application in WPF under tight deadline and delivered on schedule.• Implemented automated reviews for Medicaid program using SQL stored procedures running in overnight process that saved 25 hours per week compared to manual reviews.• Wrote application to generate letters for Medicaid assessment program. This resulted in a minimum estimated savings of 10 hours per week, as well as greater consistency and fewer instances of reprocessing compared to the original Mail Merge and spreadsheet solution.• Tuned and improved performance of SQL stored procedures as required, speeding up several by over 500 percent.• Wrote mechanism using SQL and ADO.NET for “disconnected mode”, in which an application could download information for reviews from the server while connected to the internet, disconnect and accept data entry, then reconnect and upload data. The mechanism for doing this was designed to be generic and configurable.• Designed and wrote internal training application in ASP.NET. App implemented as a shell with training topics configured in the database and consisted of one or more tests randomly generated from a set of questions. Displayed test results including correct and incorrect answers for each test.

Developed and maintained software for retail systems. Involved in all phases: requirements gathering, project planning, design, coding, documentation, technical leadership, and creating installation packages. • Led internal tools group, supervising group of three developers. • Created tool that modeled design-level metadata and generated application source code and HTML documentation for 400+ COM components, storing information in Microsoft Repository. This tool achieved a reduction in number of developers from 15 to 3.• Designed and implemented prototype design tool in C# using Windows Forms, which modeled objects and generated code through XSLT style sheets. Abstracted physical storage type using interfaces with initial implementation in Microsoft Repository. • Developed and maintained ASP.NET C# backroom retail applications for employee and register maintenance, and reporting.• Wrote code to interface to signature capture devices via OPOS drivers (Windows) and directly through RS-232 (DOS). • Attended 2000 Microsoft PDC that introduced .NET and led sessions to educate development team on .NET and facilitate its adoption.
