About
DevOps and platform engineer with 5+ years building and running Kubernetes platforms across AWS, Azure, GCP, and Huawei Cloud. Experienced in GitOps and CI/CD automation, infrastructure as code, and observability that gives on-call engineers something useful to work with. Comfortable owning a platform end to end, from cluster networking and ingress through secrets management and monitoring, and working directly with clients to get releases into production reliably.
Treats security as part of the normal workflow rather than something added on later, with RBAC, least privilege access, and scanning built into the pipeline.
Experience
DevOps Consultant (Contract) - Crafted Systems
(2025-10)
- Led deployment of a production Kubernetes platform on Huawei Cloud, owning cluster networking, ingress routing, and how services are exposed to clients.
- Set up GitOps delivery with ArgoCD so releases are declarative, versioned in Git, and easy to roll back.
- Built CI/CD pipelines in GitHub Actions covering build, test, and deploy, with SonarQube and Trivy wired in as quality and image-scanning gates.
- Configured Kubernetes RBAC, network policies, and namespace isolation to keep multi-tenant workloads cleanly separated.
- Handled API gateway routing, authentication, and TLS termination for external-facing services.
- Moved secrets out of plaintext and into Vault with External Secrets Operator, so nothing sensitive lives in the pipeline or in Git.
- Set up observability with Prometheus and Grafana, with dashboards and alerting the team actually uses to catch issues early.
- Worked closely with the backend team to stabilise service-to-service communication and wrote the deployment and handover documentation.
