Overview

Healthcare Flutter platform integrating multiple BLE medical devices — HbA1c analyzers, Lysun monitors, blood pressure cuffs, and scales — with dynamic PDF/Excel report generation and encrypted data workflows.

Challenge

Each medical device spoke its own BLE GATT dialect, and clinicians needed accurate, auditable reports — with patient data kept secure on-device across both Android and iOS pairing flows.

Solution

Abstracted 4+ device protocols behind a unified streaming layer, added encrypted local storage, and built a templated PDF/Excel report engine so clinical measurements flowed from cuff to audit trail without manual transcription.

Key work

  • BLE GATT protocol implementations for 4+ medical device types
  • Real-time clinical measurement streaming and visualization
  • Dynamic PDF report generation with customizable templates
  • Patient data management with encrypted local storage
  • Excel export for clinical audit trails
  • Native Android/iOS Bluetooth permission and pairing flows
