Project summary
Why it exists, what I built, and what I learned.
Why I built it
I wanted a practical system for turning noisy physiological data into a validated, clinically useful shunt-monitoring workflow.
What I built
Clinical and home-use sensing workflows, model-training pipelines, feature engineering, validation tooling, and FDA-support documentation.
What worked
The strongest part was connecting thermal sensor physics, model validation, and real-world patient data into one workflow.
What failed
Small and biased datasets required careful grouping, leakage control, and feature selection to avoid overfitting.
What I learned
Algorithm work is strongest when it is grounded in the sensing physics and the clinical workflow, not just model metrics.
