Ansible, AWX (custom EEs behind corporate proxy & internal CA), scheduled and on-demand ops execution

CI/CD & Delivery

Jenkins, GitOps workflows, controlled rollout to IBM WebSphere ND and container-based targets

Infra & Platforms

IBM WebSphere ND & Liberty, Oracle DB 12c/19c on Exadata & Exadata Cloud@Customer, RHEL/AIX, OCI, AWS, Kubernetes

Observability

Grafana, Loki/Promtail, GoAccess, JMX exporters, proactive drift reporting for Oracle configs

Selected Work / Impact

Scaled WebSphere ND clusters, standardized deployment procedures, and began pipeline-based rollout using Jenkins and wsadmin/Jython, reducing high-risk manual pushes.
Built AWX-driven operations platform to replace scattered cronjobs with versioned, auditable, parameterized job templates.
Automated daily Oracle config drift detection across multiple Oracle homes; generated HTML diffs, historical retention, and push alerts for audit readiness.
Deployed centralized observability (Grafana + Loki + GoAccess + Prometheus JMX exporters) for JVM health, DB state, HTTP traffic, and application logs.
