Professional Summary
Network Technician with 0 years of experience performing data center rack-and-stack, remote-hands, fiber and copper cabling, and Layer 1/2 troubleshooting; skilled with Cisco routers and switches, DWDM, SFPs, ServiceNow, and Wireshark to support production network deployments and maintenance.
Technical Skills
Work Experience
- Installed Cisco switches, routers, and DWDM equipment into assigned racks following rack elevations; connected power and patched fiber and copper, then validated reachability using SSH and Ping before handoff to engineering.
- Executed rack-and-stack QC against work orders to verify equipment position, labeling, power, and cabling, preventing physical installation issues prior to configuration.
- Processed remote-hands requests via ServiceNow: performed cable/link checks, replaced SFPs and patch cables, captured console output, and returned detailed results to remote engineers or customers.
- Isolated physical connectivity incidents by inspecting fiber links, verifying SFPs and link lights, and using Wireshark and Test-NetConnection to determine whether escalation to network engineering was required.
- Replaced failed components including SFP modules, patch cables, switches, and power supplies during maintenance windows and validated post-repair link and service restoration.
- Maintained accurate asset and cabling records in ServiceNow by updating rack elevations, port mappings, and equipment inventories after each installation or maintenance activity.
- Installed Cisco routers and switches at branch locations, completed interface checks and connectivity tests, and prepared devices for production handoff.
- Performed CAT6 and fiber cable terminations and organized rack cabling with consistent labeling to simplify future troubleshooting and changes.
- Troubleshot branch connectivity by isolating physical faults, using Ping, Traceroute, SSH, Telnet, and Dig to identify whether issues were link-layer or routing related.
- Replaced defective SFPs, damaged patch cables, and faulty network devices during scheduled maintenance and validated connectivity after repairs.
- Documented incidents and change activity in ServiceNow and Jira with detailed steps taken, test results, and updated rack diagrams to ensure smooth shift handoffs.
- Supported network upgrades by staging and provisioning equipment, verifying interface status, and performing post-upgrade validation to confirm service restoration.
Projects
- Built an Excel-based tracker consolidating rack numbers, device names, serial numbers, IPs, installation dates, and ownership to replace fragmented records.
- Used XLOOKUP, VLOOKUP, PivotTables, filters, conditional formatting, and data validation to find duplicates and produce rack location reports used for maintenance planning.
- Created standardized reports that simplified equipment lookups during deployments and reduced time spent locating devices for remote-hands tasks.
- Built a small enterprise topology in Packet Tracer with switches, routers, VLANs, static routes, and OSPF to practice configuration and failure scenarios.
- Simulated connectivity failures and used Ping, Traceroute, SSH, Telnet, and Test-NetConnection to practice fault isolation starting from physical checks.
- Captured ARP, ICMP, TCP, and DNS traffic with Wireshark and used Linux/Windows VMs to exercise IP configuration, routing, and interface troubleshooting.
