What I'm looking for

I’m looking to own cloud infrastructure end to end—Terraform + Kubernetes, secure CI/CD, observability, and cost optimization—while partnering with teams to explain trade-offs clearly and ship production-grade systems.

I’m a Cloud & DevOps engineer and multi-cloud architect with 20+ years in IT and a decade architecting and operating production infrastructure. Certified Kubernetes Administrator (CKA), I bring hands-on depth across GKE, Terraform, CI/CD, and multi-cloud environments (GCP and AWS), with a strong focus on reliability, security, and cost optimization.

As Chief Technology Officer, I led technology strategy, infrastructure, and engineering for a media and travel enterprise—designing and deploying a Windows Server–based hybrid enterprise environment spanning AD DS, Exchange, SharePoint, Hyper-V, and PKI. I also established ICT policies and security controls that reduced logged security incidents, and I introduced collaboration tooling that improved cross-functional efficiency by over 40%—all while driving a 35% revenue increase within six months.

In parallel, I freelance as an engineer and plugin developer and have built client websites, WordPress/WooCommerce plugins, and a cross-platform React Native app with client-side encryption and cloud sync. I enjoy owning delivery end to end—from IaC and container orchestration to observability, security, and rollout—while clearly communicating trade-offs to both engineering and non-technical stakeholders.
