DevOps Engineer - Indium software

(2022-12)

Developing 5G network functions to enable communication between Software-Defined Networking (SDN) components within telecom networks. The project majorly focused on developing an interaction layer between Virtual Network Functions (VNFs), essential for supporting cross-network roaming and enabling calls and messages to transit from an originator in one network to a recipient in another. By orchestrating these network functions, the project contributed to enhanced interoperability, allowing efficient service delivery and network operations across interconnected telecom infrastructures.
