I design secure delivery platforms for regulated, production-critical systems — spanning core banking, Kubernetes/OpenShift, release engineering, cloud infrastructure, and Jenkins open source.
The work I want to be evaluated on: platform scale, production responsibility, and engineering decisions that improve release safety.
CI/CD, OpenShift and Helm delivery work supporting Sacombank's successful T24 R25 production upgrade — the first successful T24 R25 core banking upgrade in Vietnam.
Reusable Jenkins/Groovy delivery patterns supporting approximately 400 source repositories across OpenShift microservices and traditional middleware platforms.
Maintaining the Jenkins integration with Ansible Tower, AWX and Ansible Automation Platform, with work across compatibility, reliability, diagnostics and security.
Reusable Jenkins/Groovy pipelines, GitLab CI, GitHub Actions, release governance, artifact promotion and multi-environment delivery.
Rolling, canary and blue-green delivery for containers, plus controlled node-by-node rollout for WebSphere and JBoss clusters.
SAST, SCA, image scanning, DAST, automated tests, approval gates and auditable production release controls.
Kubernetes/OpenShift, Helm, Argo CD, Ansible, Terraform, AWS, observability and enterprise middleware.
Public engineering work is a useful counterweight to private enterprise experience: the code, reviews and compatibility decisions are visible.
I am most useful where delivery reliability, security controls, and production constraints matter as much as deployment speed.
