· Automate routine network tasks such as configuration management, backups, compliance checks, firmware upgrades, and provisioning to reduce manual effort and improve reliability. 

· Translate network SOPs, runbooks, and BAU activities into reusable Ansible-based automation workflows(Infrastructure-as-Code) for scalable and consistent execution. 

· Implement event-driven and self-healing automation by integrating Ansible playbooks with monitoring systems, APIs, and ITSM tools to enable automated remediation and faster incident resolution. 

· Ensure network consistency and compliance by using Ansible to validate device state, detect configuration drift, and enforce standardized configurations across network infrastructure.
