U.S. Air Force veteran and CompTIA-certified IT professional (A+, Security+, Network+), AWS Certified Cloud Practitioner, finishing a B.S. in Cloud Computing at WGU. I support Windows and Microsoft 365 environments, administer Active Directory / Entra ID, automate with PowerShell, and care about doing it securely. Lately I've been building open reference projects for adding AI to Microsoft 365 environments the secure way — least-privilege, auditable, no shortcuts.

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

• Microsoft 365 & Identity — M365 Admin Center, Exchange Online, Entra ID (Azure AD), Active Directory, MFA, RBAC
• Endpoints & OS — Windows 10/11, Windows Server, Ubuntu Linux; imaging, hardware, peripherals
• Networking — TCP/IP, DNS, DHCP, VPN, SSH / RDP
• Scripting & Cloud — PowerShell, Python, Bash · AWS (EC2, S3, IAM, Route 53, CloudWatch)
• AI & automation — AI agents & multi-agent orchestration, LLM APIs, running local models (Ollama) — built behind a least-privilege, auditable boundary
• Security — SPF/DKIM/DMARC, Microsoft Defender, least-privilege, incident response, DoD 8570 (IAT II) awareness
• Blockchain / Web3 — EVM chains, wagmi/viem + RainbowKit, web3.py, ERC-20 & Solidity (Foundry), onchain USDC payments on Polygon

🔐 Microsoft 365 & Security

• secure-ai-microsoft365 — Reference architecture + working examples for adding AI to Microsoft 365 securely: least-privilege Entra apps, secrets in Key Vault, scoped access policies, a full audit trail, and the LLM kept outside the tenant trust boundary.
• m365-email-security — SPF, DKIM & DMARC + a least-privilege Microsoft Entra app, with the why behind each piece.
• 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.
• 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.

🤖 AI & automation

• building-ai-agents — A practical field guide to building & orchestrating AI agents: agent design, multi-agent patterns, evaluation, and local models — with working Python examples.
• multi-agent-research-pipeline — Turns a research question into a verified brief: fan-out research → adversarial verification → synthesis, with model tiering.

☁️ Cloud & Linux

• homelab — Self-hosted AI (Ollama + Open WebUI) on Ubuntu/Docker, accessed securely over a Tailscale mesh VPN.
• aws-cloud-projects — S3 + CloudFront static site and IAM least-privilege roles with CloudWatch alarms.
• cloudflare-dns-automation — Idempotent Python tool to manage SPF/DKIM/DMARC via the Cloudflare API.
• linux-server-bootstrap — Securely provision + harden a fresh Ubuntu server and deploy apps as systemd services.
• terraform-aws-secure-baseline — A Terraform reference module for a secure-by-default AWS S3 baseline (encryption, public-access block, versioning) + least-privilege IAM.
• 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.

⛓️ Blockchain / Web3

• wagmi-usdc-payments — A wagmi v2 + RainbowKit dApp: connect a wallet, read a USDC balance on Polygon, and send USDC with live transaction status.
• evm-onchain-toolkit — Python (web3.py) utilities for EVM chains: wallet balances, ERC-20 reads/transfers, contract calls, and message signing.
• conditional-tokens-primer — A practical primer on the Gnosis Conditional Tokens Framework behind onchain prediction markets — split / merge / redeem, with runnable examples.
• solidity-foundry-starter — Solidity fundamentals with Foundry: a tested ERC-20 token and a simple buyer/seller/arbiter escrow contract.
