Platform and Automation Tooling TeamAs an SRE at Medallia, I work at the intersection of operations and development, applying a process-oriented approach to streamline and automate workflows. My primary focus is on automating the provisioning and deployment pipeline for a multi-tenant Java application called Express (MEC). I manage infrastructure across cloud and on-premises environments, utilizing Kubernetes, Docker, and Python.Key Achievements:- Modernized the MEC (DCR) deployment process by adopting Helm and ArgoCD for managing standard Kubernetes resources.- Facilitated the adoption of DevOps and GitOps methodologies within the MEC SRE team.- Maintained and contributed to a Python-based scripting pipeline for automating operational tasks.- Actively participated in the MEC production services on-call rotation, ensuring service continuity and customer satisfaction.Skills and Technologies:- Scripting: Python/Bash/Go- CI/CD: ArgoCD, Argo Workflows, Argo Events, Jenkins, Git- Containerization and Orchestration: Kubernetes (CKA certified), Docker, containerd- Cloud: Managing services across Kubernetes clusters in cloud/on-premise environments- Release Management: Collaborating with the release management team to improve the deployment process- API Integration: Interfacing with various services via APIs enabling integration and communication between disparate systems.
