What I'm looking for

I’m looking to design and lead highly available, disaster-recovery-ready cloud infrastructure—building VMware Cloud Foundation and Kubernetes platforms while mentoring engineering teams to deliver reliable enterprise services.

I’m an Infrastructure Consultant with 6+ years of experience designing and implementing VMware Cloud Foundation (VCF), vSphere with Tanzu, NSX, and vSAN environments for banking, telecom, and stock exchange customers. I bring hands-on expertise across VCF administration and architecture, including VCF automation and operations through VCF Logs and VCF Operations.

I lead engineering teams to deliver highly available, disaster-recovery-ready infrastructure at national-bank and enterprise scale. In my recent roles, I’ve designed and implemented multiple VCF 9.02, VCF 5.2, and vSphere PR/DR environments, built VKS (Kubernetes) guest clusters, configured vSAN File Services for persistent volumes, and deployed image registries with Harbor.

I also strengthen reliability and security through Kubernetes certifications (CKA/CKS), Linux systems administration (RHCSA), and practical platform tooling like Terraform and Argo CD/Helm. I consistently focus on stable migrations (e.g., inter-vCenter vMotion), workload placement, and resilient recovery paths using Site Recovery Manager, Live Site Recovery, and vSphere Replication.
