Projects

Enterprise lab designs, plus hands-on configuration and server administration work.

  • 500+ endpoints, 10+ VLANs segmented
  • GRE over IPsec with OSPF between sites
  • ASA firewalls with ACLs, NAT, DMZ, 802.1X
Design approach
  1. Segmented 10+ VLANs and linked sites over GRE-over-IPsec with OSPF.
  2. Deployed ASA firewalls with ACLs, NAT, DMZ, and 802.1X port security.
  3. Centralized DHCP, DNS, WLC, and AAA, with Syslog for visibility.
  • 1,000+ endpoints, Core / Distribution / Access
  • HSRP + LACP for high availability
  • Dual ISPs, SSH-only management
Design approach
  1. Built a three-tier hierarchy with OSPF and per-department VLANs.
  2. Added HSRP gateway redundancy and LACP-bonded uplinks.
  3. Added a second ISP and verified failover under simulated link loss.

Hands-on Labs & Support Work
