PortugalWhat I'm looking for
I am a network and security engineer with extensive experience designing and delivering multi-site SD-WAN and segmentation solutions across global environments. I have led architecture and implementation for large M&A projects involving 400+ sites across EMEA, AM and APAC.
I have hands-on expertise with Fortinet (FortiGate, FortiManager), Cisco (SD-WAN, Meraki), and a range of monitoring and virtualization platforms including Azure, AWS and VMware. I reduce incidents through standardization, proactive monitoring and clear operational documentation.
As a former military network engineer, I bring disciplined incident response and the ability to perform under pressure, having designed and maintained tactical Cisco-based networks and coordinated technical teams. I have experience leading NSOC teams, triaging multi-client incidents, and delivering PoCs for SASE/Zero Trust enhancements.
I hold industry certifications including Fortinet FortiGate 7.6 Administrator, CCNA, and Aviatrix multicloud specialties, and I seek roles where I can architect secure, scalable network solutions and drive operational excellence.
