backend enginner
Lead cloud infrastructure design, automating base server configuration with Ansible and orchestrating multi-node Kubernetes clusters (K3s) across environments. Standardized continuous deployment by adopting a GitOps model with ArgoCD and packaging modular applications into custom Helm charts, reducing deployment drift and configuration errors. Engineered high-availability workloads and traffic management policies, configuring Horizontal Pod Autoscalers (HPA) to scale replicas dynamically under load testing and scaling Traefik Ingress controllers. Architected persistent storage and database workloads by structuring StatefulSets with PersistentVolumeClaims (PVC) and StorageClasses to guarantee database state survival across pod evictions. Designed robust cluster-wide security boundaries by implementing Kubernetes NetworkPolicies for namespace isolation, granular RBAC (Roles, RoleBindings, ServiceAccounts), and integrated Trivy scanning into CI/CD pipelines.
