AI deployment director at GEMMACON building agentic intelligence and reporting systems for automotive clients.

United States
Message

At GEMMACON North America, I design and deploy AI-driven systems for automotive consulting engagements. I built an agentic intelligence pipeline that scores signals against a defined rubric and generates briefings, along with tools that turn client JIRA exports into executive reports and resumes into client-ready profiles.

Before GEMMACON, I worked in connected vehicle software and validation at Toyota, Mercedes-Benz R&D North America, Hyundai Autoever, and PACCAR. That work covered telematics, ECU diagnostics, and HIL and vehicle testing; today, I bring that OEM experience to designing practical systems around real operational requirements.
