IT Support · Help Desk · Desktop & Network Support · Junior Sysadmin · SOC Analyst

I bring a strong customer service background and a homelab that covers the technical side: a working service desk, Active Directory, Microsoft 365 automation, Windows troubleshooting tools, a Cisco network and Splunk detections, all documented in public on GitHub.

01 About

I'm looking for my first IT role in Toronto: IT support, help desk, desktop or network support, with junior systems administration and SOC work as the next step.

My background is in customer service, which is where I learned the part of IT support that isn't technical: listening, staying calm, explaining things clearly and following through.

I earned my CompTIA Security+ in October 2026 and I'm studying for the Cisco CCNA and ITIL 4 Foundation. The homelab is where I practise the technical side, from working a ticket queue to building a VLAN network to writing the PowerShell that fixes a stuck print queue.

03 Projects

Twelve connected homelab projects. Tickets in the help desk lab point to the runbook, script or network scenario that fixes them, and the Active Directory lab is the base the rest build on.

09IT support

Help Desk Ticketing Lab

A GLPI service desk running in Docker with a queue of 25 realistic tickets from a fictional office: lockouts, new hires and leavers, printers, VPN, phishing and BitLocker. A PowerShell script loads them through GLPI's REST API, and the repo has the SLA policy, escalation template and knowledge base template used to work the queue.

Windows Desktop Support Lab

PowerShell tools for the most common desktop tickets: a slow-PC health check, a step-by-step network diagnosis, safe disk cleanup, a print spooler reset and a Windows Update repair. Plus runbooks, printer deployment with Group Policy, a sysprep reference image and remote support.

Microsoft 365 & Intune Lab

Onboarding and offboarding scripts written with Microsoft Graph PowerShell: create users with licenses and groups, then block sign-in, revoke sessions, keep the mailbox as shared and remove licenses in a safe order. Guides cover MFA with Conditional Access, Intune enrollment, compliance and BitLocker recovery.

Cisco Small Office Network

A 4-VLAN office network for Packet Tracer with 802.1Q trunks, router-on-a-stick routing, DHCP, NAT, a guest network that can't reach staff systems, port security and DHCP snooping. It comes with 12 break-and-fix scenarios written the way tickets arrive: as user complaints.

01Sysadmin

Active Directory Enterprise Lab

A two-domain-controller Windows Server 2022 forest with AD-integrated DNS and DHCP, modelled on a mid-size company: departmental OUs with delegated rights, bulk user provisioning from CSV with PowerShell, and Group Policy for password baselines, drive mappings and software restriction.

  • Windows Server 2022
  • AD DS
  • GPO
  • PowerShell

05Sysadmin

IT Automation Scripts

PowerShell tools for patch-compliance reports, audits of disabled accounts that still hold group memberships, and stale computer object cleanup (dry-run by default), plus an Ansible playbook for mixed Windows/Linux patch inventory.

  • PowerShell
  • Ansible
  • AD auditing

Infrastructure Monitoring Lab

Zabbix deployed in Docker to watch the domain controllers and endpoints, with triggers for AD DS, DNS and DHCP service failure, low disk space, sustained high CPU and unreachable hosts.

  • Alerting

SIEM Detection Engineering Lab

Windows Event Log and Sysmon telemetry forwarded into Splunk, with custom SPL detections for brute force (T1110), PsExec lateral movement (T1021.002) and encoded PowerShell (T1059.001). Each rule has notes on false-positive sources and a triage step.

  • Splunk
  • SPL
  • Sysmon
  • ATT&CK

Purple Team Lab

Runs real attacker techniques against the AD lab with Atomic Red Team: Kerberoasting (T1558.003), LSASS credential dumping (T1003.001) and encoded PowerShell. It then checks whether the Splunk detections fire and adds new rules where there are gaps.

Security Onion NSM

Network security monitoring with Zeek, Suricata and Kibana, covering what's visible on the wire rather than on the host. Traffic generated in the lab (port scans, beaconing) is triaged and written up in an analyst log.
