Where I've worked, and what I did there.

Network Engineer

Managing HSIA and enterprise networks across multiple sites: incident response, captive portal and RADIUS, Linux servers, MikroTik load balancing and ISP coordination.

• Manage and support HSIA networks serving 500+ daily users across hospitality and enterprise environments.
• Resolve 10+ network incidents daily, reducing downtime by about 30% through troubleshooting and root-cause analysis.
• Implement and maintain captive portal solutions with RADIUS authentication, improving secure guest access and session stability.
• Monitor and troubleshoot LAN, WAN and WLAN networks to keep availability high.
• Administer Linux servers (Ubuntu, CentOS): security, regular patching and uptime.
• Configure and troubleshoot Cisco, Aruba and Juniper devices (VLAN, STP, NAT, ACL, HSRP) and support Fortinet firewalls.
• Coordinate with ISPs on WAN escalations for timely resolution and SLA compliance.
• Improve Wi-Fi performance through access point placement and RF channel tuning, reducing guest complaints.
• Run periodic health checks on network devices and keep topology diagrams and configuration records current.
• Provide on-site troubleshooting and fault rectification for enterprise clients across multiple sites.
• Operate live production systems, including a captive portal gateway and a MikroTik CCR1009 load balancer, diagnosing disk-health and hardware faults.
• Resolved a routing conflict where an overly broad static route intercepted cloud-bound traffic across client sites, fixed with a targeted host route.
• Write incident reports with chronological root-cause analysis for enterprise clients.

• Trained and guided 100+ students on routing, switching and troubleshooting.
• Kept lab uptime at 99% through proactive maintenance and monitoring.
• Designed and tested network topologies for practical learning.
• Delivered hands-on training on the OSI model, TCP/IP, DNS and MPLS.
