Hi, I can take care of the embedded side of your project end-to-end. I have strong experience with ESP32 (Arduino & ESP-IDF), BLE GATT service design, and sensor integration (MAX30102, DS18B20, MPU6050). I can deliver firmware that streams data reliably to your Flutter app, with power optimization and stable BLE connection. On the backend side, I can also support with Firebase integration (Firestore, Functions, FCM) and help structure the rule-based alert engine as you described. If needed, I can assist in preparing a lightweight TensorFlow Lite model for fall detection and show how to embed it. Deliverables will include: Fully working ESP32 firmware BLE UUIDs, services & characteristics documentation Verified sensor readings into your Flutter app Firebase data pipeline + notification triggers I’ve done similar IoT health-monitoring and BLE-to-mobile projects before and can share references.

Hello, Nice to meet you! Your elderly patient health monitoring project sounds very meaningful, and I have the right expertise to handle the embedded side of it. I have extensive experience developing firmware for ESP32 and integrating sensors via BLE, including MAX30102, DS18B20, and MPU6050. I can design BLE GATT services to reliably stream data to your Flutter app while ensuring low power consumption and stable connections. I also have experience documenting BLE UUIDs, services, and characteristics clearly for mobile integration. For the fall detection feature, I can integrate a simple TensorFlow Lite model on the ESP32 to detect falls in real-time and send immediate alerts via your existing Firebase setup. My workflow ensures that sensor readings for heart rate, SpO₂, temperature, and fall detection reach the app smoothly and consistently. Do you prefer the BLE updates to be sent continuously or at fixed intervals to save power? Also, should I include calibration routines for each sensor to ensure accurate measurements before streaming? I’d love to discuss how I can help bring your project to life. Warm Regards, Bounkyo
