Oscar Alejandro Suarez Cardenas

Hello! I am a Network and Security Engineer with extensive experience designing, migrating, and securing critical enterprise infrastructures. My specialty is merging the world of traditional networks with cutting-edge Data Center architectures (SDN) and high-security environments.

I have led complex projects integrating campus and data center networks with next-generation firewalls and robust load balancing systems, ensuring high availability and business continuity.

How can I bring value to your project?

Data Center and SDN: Deployment, operation, and migration of Cisco ACI fabrics (Multi-Pod, Multi-Site, L3Out) and high-density traditional environments with Cisco Nexus (NX-OS).

Traditional Networks (Core/Routing/Switching): Robust design of campus and WAN networks using advanced routing protocols (BGP, OSPF, EIGRP) and traditional Cisco architectures.

Perimeter Security and NGFW: Implementation, advanced filtering policies, and migration of Palo Alto Networks and Fortinet (Fortigate) platforms. Native integration with Data Centers (Service Graphs/PBR).

Load Balancing and Availability (L4-L7): Configuration and optimization of F5 BIG-IP (LTM, GTM/DNS, APM) for secure application delivery.

Access Control and Visibility: Design and deployment of Cisco ISE for network segmentation, 802.1X authentication (Wired/Wireless), and TACACS+/RADIUS policies.

If you are looking for a freelance professional who understands your network from end to end (from the access switch to the perimeter firewall and the load balancer), let's talk about your next challenge!
