• As a DevOps Lead Engineer, I oversee platform, hybrid cloud infrastructures, containerization, and Kubernetes implementation, ensuring smooth operations and efficient development. Responsibilities include designing and maintaining ML search and recommendations infrastructure for scalability and reliability. I lead containerization efforts with Docker for consistent application deployment. Managing Kubernetes clusters enables automated deployment and scaling. Establishing CI/CD pipelines with Jenkins and ArgoCD facilitates rapid software updates. Infrastructure as code (IaC) practices using Terraform ensure efficient resource management. Setting up monitoring with Prometheus, Grafana, or ELK stack tracks system performance. Security measures are implemented to protect against threats and ensure compliance. Collaboration with teams ensures infrastructure meets their needs, fostering continuous learning. I act as a technical escalation point for complex issues, collaborating on incident resolution and conducting post-mortem analysis for preventive measures.
