May 2025 performance summary for uc-cdis/gen3-gitops and uc-cdis/gen3-helm. Key outcomes include cross-environment secret management (external secrets across clusters/environments), consolidated load balancing for staging and prod on a single LB, standardized naming with hostname alignment, shared resource naming across preprod and prod, and Helm-driven Karpenter node disk sizing. Notable fixes included updating the Elasticsearch endpoint and correcting a deployment script typo, improving deployment reliability. Overall impact: strengthened security posture, reduced operational friction across environments, and faster safe promotions from preprod to prod.

April 2025 focused on strengthening QA readiness and deployment reliability across two repositories by introducing an environment-root configuration and streamlining maintenance mode with a prebuilt portal. These changes improve environment initialization, reduce deployment downtime, and enable faster VA deployments.

March 2025: Delivered two targeted improvements across UC-CDIS repositories to accelerate QA readiness and stabilize cluster provisioning. Key features delivered: 1) QA Frontend Framework Setup in qa-mickey environment to enable frontend development and testing (uc-cdis/gitops-qa; commit 6b27c41501adb518d1f71c7979664add41fbc977). 2) Karpenter 1.0.8 upgrade for Node Provisioning in cluster configuration (uc-cdis/gen3-gitops; commit 39fac5104a30cd8efbc394c749f07d229df542ff). Major bugs fixed: none identified this month. Overall impact and accomplishments: enabled faster frontend testing in QA, improved reliability of node provisioning, and reduced deployment risk through up-to-date infrastructure tooling. Technologies/skills demonstrated: frontend framework integration, QA environment setup, Kubernetes cluster provisioning, Karpenter autoscaler upgrade, and strong commit-based change traceability.

Month: 2025-01 — Focused on stabilizing the system after emergent issues caused by microservices updates in uc-cdis/cdis-manifest. Implemented a controlled rollback to the previous stable baseline, restoring expected behavior and uptime. No new features released this month; primary effort centered on risk mitigation, incident recovery, and documenting the rollback process for future preparedness.

December 2024 monthly summary for uc-cdis/cdis-manifest: Delivered the Audit Service Integration into the vhdcprod environment, establishing the foundation for centralized auditing and enhanced governance. Initial setup and integration are evidenced in the commit history, marking a concrete step toward improved traceability and security across deployments.

November 2024 monthly summary for uc-cdis org: Delivered cross-repo platform enhancements focusing on scalable provisioning, observability, and governance. Key outcomes include consolidated Karpenter and EKS alignment across SKFQA, VA, and KFQA2 with AMI selector updates, migration flags, and EKS 1.31 readiness; Karpenter CRD templating and worker role naming improvements; and a Helm chart version bump to 0.2.9 for stable releases. Added audit service scaffolding in VA-testing and integrated audit-service into QA (qa-mickey) to improve traceability, monitoring, and compliance in CI/CD. Upgraded aws-es-proxy in BDcat for security and compatibility. These changes collectively improve environment parity, deployment reliability, and governance across the ecosystem.
