Network Engineer and Ethical Hacker with 8 years of experience in enterprise networking, IT infrastructure, and cybersecurity. Skilled in configuring and managing hardware and solutions from HPE, Fortinet, Sophos, UniFi, Ruijie, Cisco, and other leading brands.

Experienced in administering Linux and Windows servers, mail servers, and cloud infrastructures, including Microsoft and Google Cloud.

As the main administrator of Zabbix monitoring systems, I handle end-to-end configuration and maintenance, while also managing Wazuh for SIEM purposes. Professionally trained in ethical hacking and penetration testing, with a strong focus on identifying vulnerabilities and securing systems.

I am proficient in Python, C#, PowerShell, Bash, and other scripting and automation tools.

In my free time, I enjoy climbing, swimming, and maintaining peace of mind. I also develop web applications using Next.js and Golang, combining my passion for coding with hands-on problem-solving.

Always eager to explore new technologies, optimize IT environments, and strengthen security posture.
