Endpoint support Network troubleshooting Ticket documentation Hardware diagnostics

Focus

Support work that connects endpoints, users, and networks.

The portfolio is built around infrastructure support proof: triage, repair, document, and explain technical problems without exposing private workplace details.

01

Endpoint Recovery

Windows, macOS, and Linux troubleshooting with attention to hardware symptoms, OS issues, profile problems, and secure handoffs.

02

Network Fundamentals

Routing, switching, VLANs, subnetting, DHCP, DNS, VPN, Wi-Fi, ACLs, and packet-level reasoning for real support cases.

03

Operational Documentation

Ticket notes, incident summaries, asset checks, escalation details, and repeatable support steps written for fast team handoff.

Core Skills

Hands-on IT support foundation.

The public site stays intentionally narrow: support workflows, infrastructure fundamentals, and proof projects.

  • Windows endpoint troubleshooting
  • macOS and Linux support basics
  • Active Directory account support
  • Service desk ticket lifecycle
  • Hardware diagnostics and repair flow
  • Imaging and deployment concepts
  • TCP/IP, VLANs, DNS, DHCP, VPN
  • Wi-Fi and cabling troubleshooting

Proof Projects

Labs being documented, not inflated.

These are practical infrastructure labs and sanitized writeups designed to show troubleshooting judgment without publishing private workplace information.

In documentation

Windows Server Support Lab

AD DS, DNS, DHCP, Group Policy, user/device scenarios, and support notes built around common endpoint administration tasks.

In documentation

Small Office Network Lab

Packet Tracer topology covering VLANs, DHCP, routing, ACL behavior, failure isolation, and a written troubleshooting path.

In documentation

Incident Writeup Set

Sanitized examples for endpoint recovery, network outage triage, hardware diagnostics, user updates, and escalation notes.

Next Build

Current roadmap.

The next version should add public project pages only after the labs are documented with clean screenshots, diagrams, and repeatable notes.

  1. Publish AD/DNS/DHCP/GPO Windows Server lab notes.
  2. Publish Packet Tracer topology and troubleshooting report.
  3. Add Wireshark packet-capture walkthroughs.
  4. Add PowerShell endpoint inventory script notes.
  5. Document Intune and Autopilot learning project after lab setup.
  6. Add sanitized support-ticket case studies.
