Chala B.

I am a Senior DevOps Engineer / Cloud & Kubernetes Platform Engineer with hands-on experience designing, deploying, and operating production-grade, highly available, and secure infrastructure in regulated enterprise and banking environments. I specialize in building reliable platforms that scale — not fragile setups. My work focuses on Kubernetes, cloud-native platforms, automation, and observability, ensuring systems are secure, resilient, and easy to operate. What I Do Best • Design and operate production Kubernetes platforms (RKE2, Rancher) • Implement GitOps and CI/CD pipelines (Argo CD, Jenkins, GitLab CI) • Build golden VM images using Packer and Ansible • Deploy and secure API Gateways (Kong, Envoy Gateway) • Implement authentication and SSO using Keycloak (OIDC/OAuth2) • Design HA and rate-limiting architectures (Redis-backed, production-safe) • Build monitoring and observability stacks (Prometheus, Grafana) • Operate Nutanix AHV and VMware environments • Troubleshoot complex production issues (DNS, TLS, networking, Kubernetes internals) Enterprise and Bank-Grade Experience I currently work in a banking infrastructure environment, where reliability, security, and auditability are critical. I follow best practices such as: • Infrastructure as Code (IaC) • Immutable infrastructure • CIS OS hardening • RBAC and least-privilege access • Controlled CI/CD and GitOps workflows • Zero manual click-ops in production Selected Achievements • Built and managed multi-cluster Kubernetes platforms (Prod / UAT / Dev) • Supported 20+ production microservices with high availability • Implemented OTP rate-limiting using Kong and Redis to prevent abuse • Reduced configuration drift by standardizing golden images • Improved monitoring visibility by integrating custom Nutanix exporters • Delivered secure DMZ to internal traffic flow architectures Key Technologies Kubernetes, RKE2, Rancher, Docker, Helm, Argo CD, Jenkins, GitLab CI Nutanix AHV, VMware, Linux (Ubuntu, RHEL), Packer, Ansible Kong, Envoy Gateway, Keycloak, Redis, Prometheus, Grafana, Harbor
