Experis for Ericsson, Karlskrona
Work for Ericsson in Karlskrona, Sweden, where I was a System Developer of Cloud Orchestration and Deployment team. My work was to help develop and maintain the Revenue Manager (RM) product - next generation Charging system used by 250 telkom operators all over the world. My tasks were mostly focused on Management Server (MSV) within RM. The Management Server is the first one to install during an RM installation in a distributed, scaled and replicated manner across sites in hard consistency. Then it manages the entire installation of RM and sets up the system. The MSV is responsible for logging, fault management, and performance management of the RM system. The MSV within my responsibilities used tools like Python, Ansible, Java, Docker, Openstack, and Bash.
