Architected Python-based network automation services for thousands of Cisco, Arista, and Juniper devices across enterprise and hybrid-cloud environments. Built Nornir/NAPALM/Netmiko/Scrapli workflows for configuration deployment, operational-state collection, and compliance validation. Integrated NETCONF, RESTCONF, and gNMI for structured configuration and telemetry, and synchronized inventory with NetBox. Implemented CI-driven validation, pre/post-change checks, and rollback procedures to reduce change execution time and improve reliability.

Developed Python and Ansible automation to deploy Cisco and Juniper configurations, perform upgrades, and verify operational state. Standardized VLAN, interface, ACL, and routing changes using Jinja2 templates and vendor abstractions, and used NetBox data to drive workflows. Implemented NAPALM-based comparisons and rollback support, and automated BGP and OSPF validation using pytest embedded in Jenkins pipelines. Improved deployment speed by reusing templates and staged automated change controls.

Built Python and Netmiko scripts for configuration collection, operational checks, and automated backups. Created Ansible playbooks for repetitive switch and router updates with automated validation for VLAN consistency, interface state, and BGP neighbors. Version-controlled automation templates with Git and investigated configuration mismatches, automation failures, and network faults.

Supported Cisco routing and switching operations, including VLANs, IP addressing, and network change activities. Wrote Python and Bash scripts for device inventory, configuration backups, and network health reporting. Monitored connectivity and interfaces using SNMP, participating in incident triage, change validation, and technical documentation.
