Senior Network and Cybersecurity Specialist with 17+ years designing, defending and scaling mission-critical infrastructure for ISPs, enterprises, data centers, industry and research environments. I started in the field with point-to-point radios and microwave links, then grew into engineering leadership.
Carrier and enterprise networking is my core: BGP, OSPF, MPLS, IPv6, VLAN, VXLAN/EVPN, IPsec and SD-WAN in production. Hands-on Cisco since 2015, across routing and switching, with a strong CLI preference. I also administer Catalyst Center and Meraki through their management platforms. Multivendor by necessity and by choice: Cisco, Fortinet, Juniper, Aruba, Huawei, Nokia, Furukawa Lightera, MikroTik, SonicWall, Ubiquiti and Datacom.
As co-founder and CTO of a regional ISP, I ran the operation end to end, from backbone to billing. We scaled from a network under construction to 3,000+ subscribers with 56% average yearly growth, executed a 24x7 data center migration with no customer-perceived interruption, deployed automated DDoS mitigation via NetFlow analysis and BGP blackhole, and sustained a 24/7 SLA in production. I led a team of up to 25 people across engineering, NOC, support, sales and administration.
Today I lead network and cybersecurity engineering at Redes Tecnologia e Serviços, a multivendor integrator, where I own architecture and delivery for enterprise LAN, WLAN, security and data center projects and lead a team of six engineers. I am also the architect and technical lead of three products: our AI-driven DCIM platform, a multi-agent lead-qualification system and a new corporate ERP. I designed the company's LAN/WLAN Network Assessment methodology, and I deliver and sell it.
I combine network architecture with offensive and defensive cybersecurity, automation (Python, Ansible, Terraform) and cloud (AWS, Proxmox). My postgraduate degree in Offensive Cybersecurity formalized what was already routine: hardening, penetration testing, incident response and NOC/SOC integration.
I am practical before theoretical. What drives me is designing infrastructure that does not go down, does not leak and does not slow the business down.
Open to Senior Network and Cybersecurity Engineer, NOC/SOC Manager or Tech Lead, Network/Security Architect, Data Center Engineering Manager and multivendor technical pre-sales roles, remote, hybrid or on-site, in Brazil or abroad. Portuguese native. English at professional working proficiency (EF SET certified, C1 reading), used in technical meetings with engineering teams in Germany, in supplier negotiation with a hardware manufacturer in China, and face to face with Huawei representatives.
