I manage a multi-cloud environment across AWS, Huawei Cloud, and Hetzner, staying about 70% hands-on with the architecture and code. I lead a DevOps team responsible for the reliability, scalability, and security of our production microservices serving 1M+ active users. I also drive our CI/CD practices, cost optimization efforts, and compliance initiatives in a high-availability, multi-region setup. - **Infrastructure as Code:** Moved everything from manual console clicks to 100% Terraform. I set up GitOps using ArgoCD and Helm to keep our deployments consistent and auditable. - **Modernization:** Led the shift from a monolith to microservices for 1M+ users. I wrote a multi-runtime Helm chart that standardized how we handle scaling, probes, and networking across all services. - **Custom Tooling:** Built a custom Kubernetes operator in Go to solve a specific provisioning problem that standard controllers couldn't handle. It plugs into the existing Helm and ArgoCD delivery flow, so the resources it manages deploy the same way everything else does. - **CI/CD & Delivery:** Built pipelines using Jenkins and ArgoCD that improved deployment speed by 60%. This includes a private OCI registry and a Kong API gateway. I also implemented multi-arch builds and automated chart publishing to streamline our release process. - **Reliability & SRE:** We hit 99.999% uptime. I automated cross-region disaster recovery between the Middle East and China using Ansible and the Huawei SDK, and I run our observability stack (Prometheus/Grafana/Loki). On-call runbooks and regular DR drills are part of our routine. - **Cost & Security:** Cut infra costs by 20% while tightening security to meet PCI-DSS and SOC2 standards. This involved identity-as-code via Keycloak and hardening our WAF and VPN. We also use KMS/CSMS for secrets management to ensure our sensitive data is protected. - **Team Leadership:** I lead the DevOps team, focusing on the platform roadmap and internal training for our developers on K8s and Docker. I also handle vendor relationships and ensure our cloud strategy aligns with our business goals. ### Assistant Manager DevOps Engineer — Jordan Ahli Bank · Full-time, Oct 2024 - Feb 2026, Amman, Jordan Serving as Platform Owner for the bank's cloud ecosystem, managing 15+ AWS accounts and 20+ production microservices with a focus on high availability, disaster recovery, and fintech workload optimization in a regulated financial environment.
