  • Built a managed CI/CD platform to ensure seamless integration, deployment, security, and testing of applications throughout their lifecycle.• Built a scalable workflow engine using Temporal and Golang to automate infrastructure provisioning, Kubernetes setup, workload deployments, and day-to-day operations. It can handle hundreds of tasks concurrently• Created a test framework for the DevSecOps service using PyTest and GitlabCI, which reduced manual testing time by 93%• Experience with developing command-line interfaces (CLIs) using different programming languages, and implementing infrastructure as code. Show less • Developed web service to standardize and streamline cluster and application deployments that reduced turnaround time for Nvidia BCP cluster provisioning from days to hours• Developed an autopilot for automatic SSL certificate renewal for Kubernetes. It reduced the number of broken clusters caused by expired certificates• Developed infra as a code automation for deploying Kubernetes on NVIDIA's GPU (H100, A100, OVX, DGX)• Designed and developed a security service that enables developers to identify and resolve security vulnerabilities in their applications before release. This involved container scanning, open-source dependency scanning, static code analysis, secret detection, and infrastructure-as-code security checks• Developed Host State Management solution for software deployment in an air-gapped and non-air-gapped environment• Developed a Kubernetes upgrade controller that can upgrade Kubernetes from version N-2 to version N without disrupting long-running (> 1 week) deep learning pods. This solution allowed cluster operators to upgrade Kubernetes clusters in a transparent and zero-impact manner for customers. This solution was used to upgrade 100+ clusters from 1.18 to 1.22 with no outages.• Developed a self-service framework for tenants to onboard their resources to AWX (Ansible Tower). This solution reduced the amount of manual effort and time required for customer onboarding, resulting in increased customer satisfaction.• Built CLI for HashiCorp Vault secret migration to enable secret management in an external Data Centers• To increase speed of cluster operation and minimize downtime due to manual errors, developed automation for infra and k8s management using Ansible• Developed Jenkins and GitLab CI pipelines for automating DevOps & CICD operations• Helm charts development for Kubernetes application deployment.
