I design and operate secure delivery platforms for regulated, production-critical systems across banking, insurance, and enterprise environments.
My work sits at the intersection of CI/CD platform engineering, release engineering, Kubernetes/OpenShift, DevSecOps controls, cloud infrastructure, and core banking delivery.

- 4 years across DevOps / DevSecOps roles
- Supporting an enterprise CI/CD estate of ~400 source repositories
- Direct contributor to Sacombank's Temenos T24 R25 production upgrade, the first successful T24 R25 core banking upgrade in Vietnam
- Maintainer of the Jenkins Ansible Tower Plugin under the Jenkins project
- Hands-on with both container platforms and traditional enterprise middleware
Reusable Jenkins/Groovy shared pipelines, GitLab CI, GitHub Actions, release governance, artifact promotion, multi-environment delivery, and developer enablement.
SAST, SCA, container scanning, DAST, automated testing, approval gates, auditability, and security controls integrated directly into the release path.
Rolling, canary, and blue-green deployment patterns for container workloads, plus controlled node-by-node rollout strategies for clustered WebSphere and JBoss systems.
Kubernetes, OpenShift, Helm, Argo CD, Ansible, Terraform, AWS, artifact repositories, observability, and enterprise application platforms.
Contributed to Sacombank's successful Temenos T24 R25 production upgrade through CI/CD automation, OpenShift, Helm packaging, release standardization, and production go-live support.
My platform work includes:
- T24 R25 Transact umbrella Helm architecture
- reusable templates and 18 component/workload charts
- delivery across Develop, SIT, UAT, Staging, DR, and Production
- image and artifact promotion
- environment-specific configuration and resource controls
- CI/CD integration for packaging and rollout

One of a 4-person team supporting CI/CD for approximately 400 source repositories across OpenShift microservices, WebSphere, JBoss, and other enterprise application platforms.
The delivery platform covers multiple languages, build systems, security controls, artifact formats, and environment promotion paths.
Maintainer of jenkinsci/ansible-tower-plugin, the Jenkins integration for Ansible Tower, AWX, and Ansible Automation Platform.
Recent engineering work includes:
- resilient AAP/AWX workflow polling and transient-failure handling
- improved build diagnostics and secret-safe logging
- Job DSL compatibility fixes
- Jenkins/JDK baseline modernization and plugin compatibility testing
- UTF-8 request-body correctness
- Jenkins security scan integration
- expanded automated regression coverage
