<strong>Building production-grade cloud platforms with Terraform, Kubernetes, and SRE practices</strong>

<p>
My professional journey as a Cloud & DevOps Engineer spans hybrid AWS/GCP platforms, humanitarian cloud advisory, fintech production systems, and independent multi-cloud delivery. I specialise in Terraform-driven infrastructure, Kubernetes service delivery, SRE-style observability, and CI/CD automation with DevSecOps and FinOps baked in.
