B.S., Computer Science · Rose-Hulman Institute of Technology

Day-to-day I work with LLM APIs and multi-agent orchestration frameworks, the cloud stacks I have shipped on most recently (GCP, AWS), and the classic toolchain of product and program leadership (agile and scrum, SQL, Jira, API design, data pipelines, voice interfaces, SDLC). I keep my hands on the build, not just the plan.

Co-inventor, Operational Safety Mode (Apple). Co-inventor, Persona Menu (Microsoft).
