I'm a Director-level IT leader with 20+ years of hands-on experience designing, securing, and operating enterprise infrastructure across Microsoft and Linux environments. My background spans fintech, SaaS, healthcare, and SMB — from a 9-year Unix systems lead at a risk analytics SaaS company to building out an entire IT and security function at a fintech startup from the ground up.

I led Paynuity through a full PCI DSS 4.0.1 certification cycle — gap analysis, remediation, documentation, audit, done. I'm not just a manager who delegates it; I wrote the PowerShell scripts, mapped the controls, built the evidence repository, and sat in the audit room.

On Upwork I take on consulting work across M365 administration, email deliverability, Entra ID / Intune configuration, Linux infrastructure, and Docker-based stack deployments. I build things that actually run in production.

PCI DSS 4.0.1 — Full Lifecycle
Gap analysis → remediation → SOPs → audit evidence → certification. All applicable requirements passed at Paynuity.
Resolved a Company-Wide Email Outage
Root-caused and fixed a sensitivity label encryption misconfiguration that took down all outbound email. Full Exchange Online + OME diagnosis.
