• Collaborate with MUMPS developers to ensure compatibility with VistA standards, routines, and operational requirements.
• Develop and maintain a Visual Studio Code extension (Type Script) to support test execution, results visualization, and code coverage navigation.
• Implement features such as test discovery, execution status indicators, output rendering, and integration with local and remote test runners.
• Build and maintain a C#/.NET-based test runner for Linux environments, supporting command-line and API-driven execution.
• Integrate testing capabilities into CI/CD pipelines (Git Hub Actions, Jenkins) to enable automated test execution, reporting, and coverage tracking.
• Enhance and extend custom testing and code coverage capabilities within legacy MUMPS systems.
• Develop APIs, scripts, and tooling to support integration across systems and environments.
• Troubleshoot issues across application, infrastructure, container, and CI/CD pipeline layers.

• Solid understanding of Linux environments, shell scripting, and command‑line workflows.
• Hands‑on experience with CI/CD platforms such as Git Hub Actions or Jenkins.
• Experience designing and implementing automated build, test, and deployment pipelines.
• Experience with Docker and containerized application workflows.
• Experience working in containerized Linux environments and reproducible infrastructure patterns.
• Strong understanding of unit testing principles, methodologies, and automation strategies.
