I am an Information Technology professional with hands-on experience in infrastructure, networking, cybersecurity, and technical support. I work with corporate environments that require reliable connectivity, secure access, monitoring, and day-to-day IT administration.
I have practical experience configuring and administering firewalls, VPNs, VLANs, NAT rules, switches, network segmentation, load balancing, traffic shaping, and site-to-site VPN connections. I focus on providing secure and stable connectivity between corporate networks and remote environments.
I work with Windows Server, Active Directory, Group Policy, Office 365, GLPI, Squid proxy, and Kerberos authentication. I also administer security and monitoring solutions such as Wazuh SIEM, Zabbix, OpenVAS, Nmap, and Wireshark.
In addition to infrastructure work, I develop internal solutions and automations using JavaScript, Node.js, Express, Python, REST APIs, PostgreSQL, and SQLite. My projects include endpoint monitoring, asset inventory, alerts, dashboards, and integrations with enterprise systems such as TOTVS Protheus.
I own and operate an IT services business, supporting multiple companies with firewall deployment, network security, and VPN configuration. I combine technical support, systems administration, network engineering, and software development to deliver practical technology solutions.
