Professional Summary
Cybersecurity student with more than 14 years of technical troubleshooting experience from industrial maintenance, controls, and automation environments.
My current hands-on work is focused on networking, infrastructure, Windows and Linux systems, segmentation, IPv4/IPv6, NetBox/IPAM, reverse proxies, and security validation. The troubleshooting habits transferred pretty naturally: trace the problem, isolate variables, verify the fix, and document what actually happened.
Technical Projects
Controlled Uncontrolled Network: Full Segmentation & Remediation
Live Homelab Infrastructure • Dual-Stack IPv4/IPv6 Rebuild- Rebuilding a live multi-service homelab as an inherited network migration rather than starting from a clean slate, eliminating legacy unsegmented dependencies.
- Designed and implemented an 18-VLAN segmentation architecture with isolated security zones, dual-stack IPv6 prefix delegation (/60), and inter-VLAN firewall drop rules on a UniFi gateway.
- Migrated web applications behind an Nginx reverse proxy with strict upstream ACLs to eliminate direct client exposure to backend databases and management interfaces.
- Mapped the current architecture into NetBox DCIM/IPAM via REST API as the documented source of truth (511 passing validation checks).
- Tested access boundaries with tcpdump and positive/negative connection checks across gateway, host firewalls, and proxy layers.
Professional Experience
Maintenance Technician
Tyson Foods Inc. • West Elm Street Facility- Supported high-uptime automated food-processing operations, diagnosing electrical, mechanical, motor, and control failures in production-critical equipment.
- Traced failures from the reported symptom back to the actual cause before returning equipment to service.
- Troubleshot VFD-driven systems, low- and medium-voltage circuits, sensors, relays, and field devices under strict safety and Lockout/Tagout (LOTO) protocols.
- Documented failures, corrective actions, parts used, and repeat issues in CMMS so the next shift had a clear history of what happened.
- Coordinated with operators, sanitation, quality assurance, and maintenance leadership during live breakdowns and planned maintenance windows.
Maintenance Technician II
Chemence Medical- Maintained automated manufacturing and packaging machinery in a formally tracked 99.99% controllable-uptime medical device facility.
- Diagnosed complex robotic and control faults across ABB YuMi collaborative robots, automated bottling systems, and cleanroom negative-pressure monitoring equipment.
- Investigated intermittent failures by correlating operator-reported symptoms, alarm histories, I/O statuses, sensor feedback, and drive behavior.
- Maintained equipment in a quality-controlled cleanroom where documentation, procedure adherence, and clean restarts were required.
- Logged repair details, maintenance intervals, and equipment history in CMMS to identify recurring failure trends and improve preventive maintenance procedures.
Automation Technician
Metal Coaters / BlueScope Coated Products- Troubleshot Allen-Bradley PLC/HMI-controlled production lines (Studio 5000, RSLogix 5000/500) across continuous coated-steel processing, slitting, and material-handling operations.
- Maintained and diagnosed FactoryTalk HMIs, PowerFlex VFDs, field sensors, line motors, interlocks, and feedback devices affecting line speed, tension, and product quality.
- Used electrical schematics, live equipment behavior, I/O states, and process conditions to isolate whether faults were electrical, mechanical, logic-related, or process drift.
- Performed post-maintenance startup validation with production and quality personnel, confirming equipment stability before release to continuous operations.
