I build the full stack, and I mean all of it. Circuit boards, operating systems, server infrastructure, web applications, AI platforms. Over 15 years I've shipped FDA-regulated medical devices, assembled bare-metal GPU inference nodes, built an AI appliance that puts 1,100+ tools across 75+ modules behind a single agent, founded two businesses, and built everything in between.

My career started at National Biological Corporation, where I designed Class II phototherapy devices and authored FDA 510(k) submissions. That regulatory rigor, formal risk assessments, verification protocols, traceability, still shapes how I approach every project. When I built the USI platform, the security model got the same scrutiny as a medical device: tiered authorization, cryptographically signed identity between services, audit logging, and an operator gate in front of anything destructive.

USI is patent pending (US Provisional Application No. 64/029,948) and runs in production on a paying client's own hardware, alongside my primary system and a demonstration unit. That same fleet is where I run a detection and response practice: vulnerability advisory triage against a live inventory, YARA rules written and benched against real corpora before anything is trusted, mail authentication hardening after a phishing campaign, and same-night response to a critical vulnerability in an internet-facing service.

Today I run Sunrise Consultants and Sound Grounds Coffee Shop, both out of Sandusky, Ohio. The consultancy specializes in AI integration and systems architecture. Sound Grounds is a tech-forward cafe where I designed the POS, the recording studio, the digital signage, and the streaming infrastructure. It's both a business and a proving ground for every venue technology service I offer.

What makes my work different is the range. Most engineers specialize. I cross disciplines because real problems do. A client who needs AI connected to their business systems also needs the server hardened, the network segmented, and the deployment automated. I handle all of that because I've been doing all of that, from hardware bring-up to production monitoring, for my entire career.
