I build and support resilient DevSecOps platforms, CI/CD pipelines, and enterprise infrastructure.
South AfricaWhat I'm looking for
I support DevSecOps platforms, CI/CD toolchains, and enterprise infrastructure at Sedibelo Marketing and Trading & SediLINK.
I monitor GitLab and containerized environments, investigate pipeline failures and infrastructure incidents, and document root causes and resolutions. I also coordinate tool upgrades, patch management, and SSL/TLS certificate renewals.
I deploy containerized applications with Docker and Docker Compose, build GitLab CI/CD pipelines, and configure Nginx reverse proxies for Node.js services. My infrastructure work includes ArangoDB high-availability clusters, Shell and PowerShell automation, Linux firewalls, DNS, domains, and IP address management.
Previously, I supported mine-site systems at Sedibelo Kgabo Mining, improving operational resilience through monitoring, troubleshooting, and incident response. I’m currently pursuing Microsoft AZ-104: Azure Administrator certification and have completed Cisco Networking Academy cybersecurity training.
