What I'm looking for

I'm looking for remote infrastructure, cloud, DevOps, or SRE work where I can build reliable multi-cloud platforms, automate delivery, improve observability and security, and support production systems across Africa/Europe-friendly hours.

I've delivered and operated production cloud infrastructure for Capitec Bank, Mr D, Polygon Technology, Western Cape Government, AWS customers, and contract clients through Nameless.

At Mr D, I improved Amazon EKS operations, on-call workflows, developer enablement, and Grafana-based observability for high-traffic digital commerce systems. At Polygon, I supported mainnet and testnet infrastructure, multicloud automation, monitoring, incident response, and recovery during the 2021 Polygon PoS chain freeze.

I build repeatable AWS and Azure platforms using Terraform, Ansible, Kubernetes, Docker, CI/CD, monitoring, and secure access patterns. My work spans serverless APIs handling millions of requests, banking DevOps workflows, transaction pipelines, local/devnet environments, and operational handover.
