At CACI’s NASA GDS team, I cut API response times from 60–300 seconds to an average of ~300ms by enforcing strict schema constraints. I designed a unified service layer that reduced business logic duplication and the codebase by ~20%, and I’m leading the migration from a monolithic application to an API-first design with a React.js frontend.

At WellCaddie.com, I co-founded the company and served as CTO and lead engineer, building an IoT monitoring platform that processed 500,000+ sensor entries per day and maintained 99% uptime across four states. I also co-invented two awarded patents and built OverlayHQ.com, a streaming overlay platform that reached 2M+ viewers within its first year.
