01The challenge

What we were asked to solve.

Patients with chronic conditions juggled 4–6 portals, paper logs, and inconsistent advice. The founder needed an MVP polished enough to attract a clinical pilot, on a YC budget.

02The solution

What we shipped.

We shipped a SwiftUI + Kotlin Compose app sharing a typed schema and a small Rust core for symptom math. A clean weekly digest replaced four separate care-team emails.
