IT Infrastructure · Cybersecurity · Agentic AI Automation
I design, harden, and defend the systems small and growing businesses run on — from ground-up network builds to cloud and on-prem security to AI agents that automate the work that eats your week. One point of contact. No handoffs, no help-desk queue.
What I Do
From a single office network to a full ground-up build, I design infrastructure that's documented, backed up, and hardened from day one — not patched together after something breaks.
Risk assessments, identity and SSO hardening, endpoint protection, and Zero Trust DNS filtering — practical security grounded in CISA small-business guidance, not checkbox compliance.
AI agents that handle repetitive business workflows end to end — from Meta and Facebook ad campaigns to routine operations — so the work runs on its own instead of eating your week.
Recent Work
Client names and identifying details are withheld out of respect for confidentiality — especially where the work involved an active security incident. The scope and outcomes below are real.
Legal Industry
A regional law firm needed assurance that a ransomware attack could never take down client case files. I designed and deployed a ransomware-resistant backup architecture using immutable, offsite snapshots — guaranteeing a clean recovery point exists even if the network itself is compromised. That's phase one of an ongoing security roadmap being rolled out in stages: hardened backups first, then DNS and email authentication (SPF, DKIM, DMARC) to stop spoofing and phishing, followed by identity and single sign-on hardening firm-wide.
Construction Industry
When a growing construction company had employee accounts compromised through password reuse, I stepped in to contain the active breach, lock out the attacker, and secure every account within hours. From there, I rebuilt their environment on a modern, cloud-first security foundation: Microsoft 365 Business Premium with Entra ID, Intune device management, and Defender threat protection; a company-wide password manager rollout to eliminate reused credentials; and Zero Trust DNS filtering — all aligned with CISA's small-business cybersecurity guidance.
