• Developed a Golang-based Kubernetes Operator to backup diverse databases and technologies at the application level, leading to a 30% reduction in backup-related downtime and improved data protection.
• Orchestrated the deployment and management of Rook Ceph clusters on four Kubernetes clusters, efficiently managing 200 TB of data across block storage, object storage, and file system modes and leveraging OpenEBS on.
• Enabled Cache Pool implementation on Rook Ceph clusters and Cache Slice Module on Nginx, resulting in an exceptional 60% reduction in average response times for the object store, facilitating a client throughput by 2x.
• Provided GitOps solution using Terraform, Ansible and ArgoCD combined with Gitlab-CI to separate the setup and configuration of 40+ managed services.
• Implemented a GitOps solution using the ArgoCD apps-of-apps pattern to establish version control for all Kubernetes resources across five Kubernetes clusters, including 120+ microservices. Reduced manual interference.
• Created a Python API to generate most staging/production requirements of developers, such as Gitlab-CI, Dockerfile, and GitOps structure that decreased 90% of project deployment time.
