U.S. Air Force veteran and CompTIA-certified IT professional. I run help desk and Windows / Microsoft 365 support today, and I'm building toward cloud and security engineering — least-privilege, auditable, documented so the next person doesn't have to guess.

🟢 Open to IT Support / Help Desk / Systems Administration roles in Chicagoland (on-site or hybrid).

☁️ Cloud

• aws-cloud-projects — Hands-on AWS labs: S3 + CloudFront static site and IAM least-privilege roles with CloudWatch alarms.
• terraform-aws-secure-baseline — Terraform reference module for a secure-by-default AWS S3 baseline (encryption, public-access block, versioning) + least-privilege IAM. fmt / validate clean.
• cf-workers-ai-digest — A scheduled digest on Cloudflare Workers: a cron trigger runs a Workers AI model and posts the result to a webhook, with a secret-gated preview-before-post path and no external API key. Unit-tested.

🔐 Security

• webhook-auth-patterns — Authenticating inbound webhooks the right way: shared-secret, HMAC-SHA256, and Ed25519 — timing-safe, replay-resistant, with runnable examples.
• m365-email-security — SPF, DKIM & DMARC plus a least-privilege Microsoft Entra app, with the why behind each piece.
• dmarc-report-analyzer — Parses DMARC aggregate (RUA) reports into a readable summary: SPF/DKIM alignment, per-source breakdown, and top failures. Stdlib-only Python, tested.

⚙️ Automation

• powershell-it-toolkit — Help-desk + M365 / Active Directory automation (onboarding, offboarding) and Windows performance diagnostics (health report, page-file, cache cleanup).
• ad-automation-toolkit — PowerShell for Active Directory admin: bulk onboarding, offboarding, stale-account reports, and group audits — Pester-tested, with -WhatIf support.
• net-triage — A help-desk network triage CLI: DNS, TCP ports, HTTP, and latency checks rolled into a PASS/WARN/FAIL report. Stdlib-only Python, tested.
• kb-health — An LLM-powered linter for a folder of Markdown docs: finds contradictions, orphan pages, stale claims, and missing topics, then writes a report. Stdlib-only Python CLI.
• job-alert-bot — Multi-source job-listing alert bot: polls USAJobs, Adzuna, SerpAPI, and Greenhouse/Lever boards, scores postings with deterministic rules, dedups in SQLite, and delivers a Telegram digest. Tested, with a systemd deploy.

🖥️ Self-hosting

• homelab — Self-hosted services on Ubuntu / Docker, accessed securely over a Tailscale mesh VPN.

Deepening AWS (IAM, networking, infrastructure-as-code with Terraform) and security fundamentals while finishing a B.S. in Cloud Computing at WGU.

_{Air Force Security Forces veteran → IT. I like fixing things, locking them down, and writing it down so the next person doesn't have to guess.}
