PROFILE

Aaron Chapman

Worked on the CDCgov/NEDSS-Helm repository to enhance deployment reliability and environment consistency by maintaining and updating Helm charts for NiFi EFS. Focused on image tag upgrades and version pinning using YAML and Helm, ensuring that deployments consistently used the intended snapshot images across environments. Addressed deployment drift and improved release predictability by aligning chart definitions with tested builds, reducing the risk of version mismatches during upgrades. Leveraged DevOps practices, Git-based change management, and CI/CD alignment to streamline testing and production workflows. The work enabled faster QA cycles, reproducible deployments, and strengthened traceability for downstream releases and audits.
