Developed automated certificate enrollment and device management security protocols for the MaheshGSLAB/ansible-avd repository, focusing on secure, hands-off provisioning and lifecycle management. Leveraged Ansible and YAML to integrate EST-based security protocols, enabling consistent device configurations and reducing manual intervention. Collaborated with multiple contributors to ensure code quality and knowledge sharing throughout the feature’s development. The solution enhanced auditability and compliance readiness by automating certificate lifecycle processes, strengthening network security and policy enforcement. By integrating with eos_cli_config_gen, the work streamlined device onboarding and management, demonstrating depth in configuration management, DevOps practices, and network security within a collaborative engineering environment.
