TECHNICAL OPERATIONS · TAMPA, FL

I keep your systems running — and build the ones you're missing.

About Me

I'm a technical operations specialist based in Tampa, FL. I keep the systems businesses depend on running — point-of-sale, networks, AV — and I build the software when what you need doesn't exist yet. Army veteran, 8 years in the Reserve including a deployment to Poland. Before this I was a technical operator at Knolls Atomic Power Laboratory, running and maintaining a pressurized chemical system in a Naval Reactors facility where a missed step could cost someone their life. That's where I learned to follow procedure, document everything, and never guess. Now I deploy POS systems at live music festivals processing thousands of real-time transactions, stand up wifi networks in open fields, run AV and lighting for events, and build full-stack applications with authentication, payments, and real production traffic. Whatever keeps your business operating — I can install it, fix it, or build it.
