Role: Flutter Developer
Key Features
- 01Developed the mobile module that captures real-time camera data when the user places their finger on the rear camera. Implemented logic to process high-frequency pixel data and convert it into a raw signal suitable for pulse and HRV analysis, which was then passed to the signal processing algorithm developed by another team member.
- 02Visualized the processed pulse and HRV data in real time using the fl_chart library, providing users with interactive and easy-to-read charts.
- 03Reusable UI components were created following atomic design principles.
