What I'm looking for

I'm seeking a fully remote Network & Security Engineer role where I can leverage 8.9+ years of experience with Cisco, Fortinet, Palo Alto, Check Point, Meraki, Azure, VMware, and Linux. I specialize in routing & switching, SD-WAN, VPNs, firewalls, and enterprise networking, and I'm eager to help global teams build secure, scalable, and resilient infrastructure.

I am a Network & Security Engineer with 8+ years of experience designing, implementing, and supporting enterprise network and security infrastructure in mission-critical environments. My expertise spans routing & switching, firewalls, VPN technologies, SD-WAN, cloud networking, and network operations.

Throughout my career, I have worked extensively with Cisco, Fortinet, Palo Alto Networks, Check Point, Cisco Meraki, VMware, Linux, and Microsoft Azure. I have designed and managed secure enterprise networks, implemented site-to-site and remote access VPNs, configured advanced routing protocols (OSPF, BGP, EIGRP), managed high-availability firewall deployments, optimized network performance, and resolved complex L2/L3/L4 networking issues.

I hold CCNA, CCNP Security, and Microsoft Azure Security Engineer (AZ-500) certifications, demonstrating a strong foundation in both traditional networking and modern cloud security. My experience includes enterprise network operations, incident management, change management, troubleshooting critical production issues, and collaborating with cross-functional teams to deliver reliable and secure infrastructure.

I enjoy solving complex networking problems, improving network resilience, automating operational tasks, and staying current with emerging technologies such as Zero Trust, SASE, cloud networking, and infrastructure automation. I am passionate about building secure, scalable, and highly available network environments while continuously learning and expanding my expertise.

I am currently seeking fully remote opportunities with global organizations where I can contribute my experience in enterprise networking, network security, cloud connectivity, and infrastructure operations while continuing to grow as a technical professional.
