I am a systems and telecommunications professional with long-term experience in RF systems, embedded technologies, and communication infrastructure design and integration.

My work spans both technical development and system-level coordination activities in complex communication environments, including mobile networks, RF systems, and mission-critical infrastructures.

I have been involved in GSM-related technologies, RF system analysis, and the integration of VoIP/RoIP and disaster recovery solutions for distributed communication systems. In several contexts, I also worked in a technical project management role, coordinating internal teams, external contractors, and system vendors for the delivery and consolidation of large-scale communication infrastructures.

A significant part of my professional activity has taken place in industrial and security-related environments under confidentiality constraints, which limits what can be shared publicly.

The projects available on this GitHub represent personal work developed for study, experimentation, and practical engineering problem solving in embedded systems, RF, networking, and software-defined systems.
