As part of 13NET Inc., I worked as an engineering contractor supporting Comcel S.A. in spectrum regulation and transport network documentation. This role marked the beginning of my telecommunications career, providing hands-on exposure to microwave link legalization, RF validation, and transport network administration. Core Responsibilities Prepared, reviewed, and submitted requests for microwave link legalization before the MinTIC, ensuring compliance with spectrum allocation policies. Conducted technical analysis and validation of microwave links approved by MinTIC against Comcel’s deployed network, identifying discrepancies and proposing corrections. Administered the transport network documentation tool covering microwave, fiber optic, and satellite infrastructures, providing accurate and updated records for network planning, operations, and regulatory reporting. Collaborated with Comcel’s engineering and regulatory teams to ensure consistency between field deployments and spectrum approvals. Key Achievements Enhanced Comcel’s regulatory compliance processes by ensuring all microwave link submissions matched the actual deployed network. Improved accuracy of transport network documentation, supporting decision-making for future LTE and backhaul planning. Built strong expertise in spectrum management, RF validation, and transport network documentation, which facilitated my direct transition to Comcel in 2010. Developed a working understanding of vendor coordination and the operational challenges of managing a nationwide mobile transport network.

I specialized in telecommunications, network architecture, and radio propagation. My academic focus included Digital Terrestrial Television (DTT) and WiMAX, which were emerging technologies at the time. These studies built a strong foundation in propagation modeling, spectrum management, and interference analysis, later applied to LTE/4G, 5G, and IoT networks. I also developed expertise in MATLAB for system simulation, digital signal processing, and traffic optimization, as well as networking, IP/MPLS transport, and multiple access systems (CDMA). This combination of theory, simulation, and applied projects provided the analytical and technical background that shaped my career in mobile networks, spectrum management, and large-scale connectivity programs.

Bachelor’s degree in Electronics Engineering with focus on telecommunications, signal processing, and electronic systems. Academic projects covered circuit design, control systems, digital communications, and propagation fundamentals applied to early wireless technologies. Acquired skills in spectrum analysis, coding, MATLAB-based simulation, and process optimization, which later provided the foundation for my MSc and professional career in mobile networks, spectrum management, and large-scale telecom projects.
