PROFILE

Dave G

During four months on greenriver/hmis-warehouse and greenriver/hmis-frontend, Dan Greiner delivered features and fixes spanning backend, frontend, and CI/CD automation. He transitioned System Performance Measures to FY2026 by updating models, configurations, and migration controls in Ruby on Rails, ensuring accurate reporting and data lineage. Dan improved metrics observability by instrumenting and later rolling back Yabeda metrics to maintain production stability, and enhanced reporting reliability by refining error handling and logging. On the frontend, he automated Docker image publishing via GitHub Actions using JavaScript and YAML, streamlining releases. His work demonstrated depth in data modeling, configuration management, and testing.
