• Developed and documented a Workstation Snapshot Automation, Python library. It uses automation that leverages Kubernetes OpenShift to schedule and execute system config snapshots for Windows workstations. Utilizing WinRM for remote connections, integrating GitLab for version-controlled change tracking and historical data management.• Designed and implemented a scalable OpenShift cluster creation and management system using ISO-based installation, Ansible automation, and GitOps practices with ArgoCD, enabling declarative configuration and automated deployment for multiple clusters with custom configurations.• Designed and implemented utility automation for deploying a containerized DHCP server using Docker, Kubernetes, and NMState, streamlining VLAN config and network attachment through automated CI/CD pipelines and ConfigMap-driven dynamic server configurations. Automated a variety of other internal utilities in much the same manner.• Architected and implemented a Python and Django-based Network Mapping and Management API suite, implementing features for automated device , network topology visualization, real-time monitoring, and inventory management using RESTful services, Nornir, and NAPALM.• Managed multi-tenancy Kubernetes cluster deployments and continuous delivery pipelines using ArgoCD, GitOps-based automation, efficient environment synchronization, and real-time monitoring of application states while providing support for various clients, including 5G ORAN implementations, and other scientific engineering.• Developed and deployed a lab equipment inventory and scheduling app using Python/Django and PostgreSQL, containerized, and deployed on OpenShift, streamlining internal processes from manual MS Excel sheets. - Layer 2 & 3 networking.
