As a Telecom Operations and Maintenance Specialist, I ensure the smooth functioning of our Core CS and Core IMS Networks, focusing on VoLTE services. My responsibilities include equipment integration, tests, configuration, updates, upgrades, and L3 support across TIM Brazil's network.- Network Management: I manage multiple network elements (MSC, MGW, HLR, SBC, IBCF, E-CSCF, ATCF, SPG, I/S-CSCF, ATS, PCRF, ENUM/DNS, CCF, MRFP/MRFC, HSS, CUDB, EMA/EDA, IP SMS GW, CSFB, 5G EPSFB), ensuring optimal performance and minimal downtime.- Troubleshooting and Support: I troubleshoot and resolve issues related to the virtual environment, including vCloud, vCenter, vROPS, and VMWare. Additionally, I analyze Network Trouble Tickets (NTTs) and identify and implement solutions to reduce their frequency and impact.- Monitoring and Automation: I utilize Zabbix and Grafana for monitoring key network performance indicators (KPIs). This setup allows for real-time tracking of network health, and I have implemented alerts via Telegram to notify the team of any performance degradation. Furthermore, I have automated the generation of weekly reports using Python, enhancing our ability to monitor and improve network performance.- Projects and Implementations: I led the implementation of the 9th digit in Brazil's mobile service and am skilled in BSC/RNC migration and ITX route configuration.- Analytics and Reporting: I analyze KPIs for VoLTE and CORE CS using tools like SQM, Netchart, Altaia, Service Now, U2000/U2020/MAE, and Telcomanager, developing reports to improve network performance.- Professional Growth: I'm pursuing skills in Python and JavaScript to enhance my technical expertise.- Flexible Hours: Experienced in on-call and night shift duties, working outside traditional business hours.
