Bridging Support & Engineering

With 20+ years in IT Operations and Software Development, I don't just ticket issues—I solve them at the code level. I leverage my background as a former C#/.NET Developer to diagnose root causes in stack traces and SQL queries, reducing escalation times for critical defects.

My Mission: I combine the operational discipline of a US Navy Veteran, with modern Cloud fluency (GCP & Azure) to ensure system reliability and stability.
