Currently working on a fully AWS-based project which processes medical attachments related to claims, handles EDI X12 batch files, supports REST-based APIs, and provides web-portals for medical payers and providers. Work on this project involved the creation of multiple Spring Boot APIs, and the maintenance of large datasets on Dyanamo DB. DevOps related tasks such as GitLab CI/CD management, the creation of Python lambda functions to support development were also key features of this project.

InCEP (Integrated Centralized Execution Platform) is an Enterprise Performance Management (EPM) application which provides planning, tracking, reporting and real-time analysis capabilities used by federal agencies, including the Department of Health and Human Services (HHS), Department of Veterans Affairs (VA), US Food and Drug Administration (FDA) and Office of the National Coordinator for Health Information Technology (ONC). This migration project involved development of a new MVC style application using JSF (PrimeFaces) as the older JSP application was gradually decommissioned.

CMMI (Centers for Medicare and Medicaid Innovation) supports the development of pilot healthcare payment and service delivery models (HHVBP, AHC, EPM, EMTM, etc.), regionally. If successful, they are scaled up, nationally. The Reusable Framework (RF) project involved the development and support of a solution which would provide infrastructure for implementing future CMS innovation models, as well as supporting existing ones, reducing redundancy and maintenance of shared business functions. I worked on the CDX (Centralized Data Exchange) team, which handled file processing, utilizing Spring Web Services, Spring Batch, and IBM MQ - deployed on IBM's WebSphere Application Server, with version-control hosted on GitLab, and persistence on an Oracle database.
