I build secure, governed multi-cloud platforms and automate migrations, identity, and infrastructure delivery.
What I'm looking for
At Valtech, I lead multi-cloud governance, tenant-to-tenant migrations, identity automation, platform modernization, and cloud security for enterprise customers across Azure, AWS, and GCP.
I build repeatable Infrastructure as Code solutions with Terraform, automate identity lifecycle processes through Adaxes, and improve cost visibility through FinOps models and cloud tagging strategies. My work spans Microsoft Entra ID, RBAC, Conditional Access, Privileged Identity Management, policy enforcement, networking, and secure platform services.
Previously, I led Azure integration and migration work at Visa, delivered secure Azure architectures at Quisitive, and enabled DevOps pipelines for IBM i environments at ARCAD Software.
I’ve grown from IT support through infrastructure engineering into cloud and DevOps work, bringing an operational mindset to scalable, resilient, and highly available platforms. I enjoy solving complex infrastructure challenges and helping engineering teams deliver faster and more securely.
