Network Design & Simulation

• Designed and simulated enterprise-grade LAN/WAN networks in Cisco Packet Tracer, optimizing traffic flow and redundancy.

• Configured routers, switches, and firewalls with OSPF, VLAN trunking, and STP protocols.

• Implemented network security policies: ACLs, firewall rules, and VPN tunnels (IPSec) between sites.

• Built a site-to-site VPN tunnel between two firewalls with encrypted data transmission.

• Diagnosed and resolved complex network issues: IP conflicts, routing loops, and DHCP failures.

• Validated network reliability through stress testing and packet analysis.

Network Infrastructure Project:

• Designed and implemented a secure VPN tunnel between two firewalls using Cisco Packet Tracer, enabling encrypted communication between separate networks.
• Configured access control lists (ACLs), encryption protocols (IPSec), and routing tables to ensure secure data transmission.
• Tested and optimized tunnel performance by analyzing packet flow and troubleshooting latency issues.

Assisted clients in developing business continuity plans, ensuring minimal disruption during unexpected events or crises.

Created and implemented innovative virtual training tool to support surveillance and security of facilities and premises.

Increased quality control by monitoring materials for compliance and to eliminate process lags.

Reduced security risks by providing efficient emergency response management.
