As a passionate Telecommunications Engineer, I have developed extensive hability in managing, optimizing, and troubleshooting Core Network and Radio Access Network (RAN) systems across diverse environments. My professional journey, including key roles at Africell Angola and Digis Squared Technology, has equipped me with the skills necessary to ensure seamless voice and data communication for both local and roaming subscribers.At Africell Angola, my current role as a Core Network Engineer involves ensuring the smooth performance of CS&PS and RAN nodes through proactive hardware and software management. Good trace analysis skills (ISUP, SIP, SCCP, MAP) to detect and resolve signaling issues that impact call reliability and roaming. I also have a strong background in integrating new network sites/cells in core and RAN nodes, conducting IREG tests with international partners, and maintaining service quality through continuous optimization efforts.Previously, as a Front Office Engineer at Digis Squared Technology, I developed a robust understanding of network KPIs (CSSR, HOSR, DCR, throughput) and played a crucial role in troubleshooting and maintaining Core and RAN elements. My ability to identify and resolve node congestion, signaling issues (SS7, SIP), and other network challenges has consistently enhanced network performance and user satisfaction.I pride myself on my analytical problem-solving skills, team collaboration, and leadership in implementing solutions that drive efficiency and reliability in telecommunications networks.
