Developed and delivered Ericsson RAN to 5G Core integration for the Athens site, leveraging the Athens Route-Manager API within the 6G-Library repository. This work enabled dynamic routing and end-to-end connectivity between RAN and core networks, reducing manual configuration and improving deployment speed across multi-site environments. The approach emphasized API-driven integration and modular component design, using technologies such as Ansible, Terraform, and Python to automate infrastructure provisioning. The release process followed a pull request-driven workflow, consolidating the new feature into Release v1.1.0. This contribution enhanced routing reliability and supported scalable, collaborative DevOps practices for cloud infrastructure projects.
