Senior RF & Network Operations Engineer

Monitored and analyzed LTE, 5G, and FTTH KPIs across regional LATAM alliances, identifying anomalies and coordinating corrective actions with internal teams and external vendors. Performed root cause analysis (RCA) on service-impacting issues and managed technical escalation workflows to ensure SLA compliance. Designed and automated operational dashboards in Power BI with ETL data pipelines, improving real-time visibility of network performance trends. Produced structured technical reports and post-mortem documentation for incident tracking and continuous improvement.

Led technical teams across Colombia and Argentina supporting LTE, 5G, and FTTH network deployment, optimization, and troubleshooting of service-impacting incidents. Coordinated remote troubleshooting sessions with field engineers and vendors, analyzing logs, KPIs, and RF parameters to isolate and resolve network faults. Managed incident escalation workflows, prioritizing critical outages and maintaining structured communication with technical stakeholders and vendor partners. Supported deployment readiness and post-implementation performance validation for new network sites, coordinating end-to-end service acceptance activities. Mentored junior engineers in troubleshooting methodologies, KPI interpretation, and 3GPP LTE/5G standards. Produced regulatory reports for MinTIC, ANE, and CRC, ensuring 100% compliance with national telecom requirements.

Planned, deployed, and optimized LTE TDD networks in Colombia, analyzing Drive Test results and RF parameters (RSRP, SINR, PCI, MCS, Throughput) to improve coverage, capacity, and mobility. Optimized RF parameters including handovers (intra/inter-frequency), neighbor lists, PCI planning, power control, and load balancing. Used Infovista Planet, DataManager, and TEMS for performance analysis, coverage simulation, and optimization planning. Collaborated with deployment and core network teams on new site integration, supporting end-to-end service validation and commercial coverage acceptance.

Supervised new LTE site on-air activities, Drive Tests, physical optimizations, and technical acceptance validations. Analyzed RF parameters and KPIs to certify coverage and service quality of new network sectors entering commercial service.

Performed 2G, 3G, and 4G network optimization through Drive Test and Walk Test analysis using TEMS, adjusting RF parameters and antenna configurations to improve network quality. Produced technical reports with KPI analysis and recommendations coordinated with vendor teams.

Executed nationwide technical validations for LAN connectivity, structured cabling, routers, modems, and end-user equipment for the Compartel government program. Performed on-site troubleshooting of network connectivity issues and validated site readiness for service activation.
