Experience and ongoing training

I have spent several years working in IT, supporting personal computers, networks, and users in small businesses and private environments. In parallel, I actively build my cybersecurity skills through hands‑on labs (such as TryHackMe) and real work with tools like Wazuh, RMM platforms, and Microsoft security technologies. The goal of this ongoing training is to deepen my knowledge of security operations (SOC) and bring powerful open‑source security tools to smaller organizations.
