4 days. One idea. A fully functional prototype. ReEntry started with a simple question: What happens to concussion recovery between appointments? Over the last 4 days, I took that idea and built ReEntry into a working mobile-first app connecting the student → clinician → school recovery loop. Some of what I shipped: • Low-friction activity & symptom logging • Voice-assisted capture with user confirmation • Smart Capture based on school schedules • A longitudinal Tolerance Map & Journey • Personalized, evidence-linked ML with explainability • Separate student, clinician & school workflows • Privacy-aware school accommodations & ReEntry Pass • Database-level role/access controls One design principle guided the entire build: AI should help organize evidence — not make medical decisions. When there isn't enough evidence to responsibly surface a pattern, ReEntry surfaces nothing rather than pretending to know. Still a prototype, still plenty to learn and improve — but I'm incredibly proud of how far ReEntry went from idea → working product in just four days. Return to school. Return to friends. Return to life.
