Hi , I'm Kevin Marin
Hey, I'm Kevin, a Data Science student at Claremont McKenna College (Class of 2026). I like the whole arc of a problem: turning a vague question into a clean dataset, a model, and something a person can actually use.
My flagship project, MetricPath, is an AI health CLI that runs a logistic mortality-risk model trained on NHANES data behind a conversational LLM intake, and it runs fully local for privacy. I also ship web apps and internal engineering tooling, and I'm currently sharpening my SQL and ML system design while prepping for interviews.
