Overview
A wristband, an optional ring and an app for people living at home: it keeps quiet watch and tells their family when something looks wrong — a fall, a critical reading — with step-by-step first aid, in Arabic and English. It grew from my MedGuard graduation project.
What I built
- Rebuilding my MedGuard graduation project (Flutter + Firebase, BLE heart rate, Gemini health analysis, GPS emergency alerts) as a family-safety wearable: a wristband, an optional ring and an app.
- The companion app tracks vitals against personal baselines, alerts carers on falls and critical readings, and guides first aid step by step, in Arabic and English.
- New backend on Fastify, PostgreSQL and Valkey, replacing Firebase; first builds uploaded to the Google Play testing track and TestFlight.
- Built shieldkin.com: a bilingual product site with a scroll-driven 3D wristband in three.js.
- Designed the wristband case in code (build123d to STL/STEP), 3D-printable for fit-and-feel testing, with Blender renders and an interactive web 3D viewer.
- Wrote the device specification: sensors, display and buttons, connectivity, battery and materials.
