About Me
I’m Bruno Willian de Oliveira, an IT Manager with 12+ years of experience designing, implementing, and securing LAN, WAN, and Internet services for multi-site enterprise environments. I specialize in Cisco and Fortinet solutions — routing, switching, VPN, wireless, and next-generation firewalls.
I launched bwotec in January 2026 to share hands-on technical knowledge from real-world projects and lab environments. Every article here comes from practical experience, lab testing, and a genuine passion for understanding how networks and security work under the hood.
