50+ clinics expand access to remote care.
Engineering a HIPAA-compliant telehealth platform connecting FDA-approved Bluetooth vitals hardware, real-time WebRTC video consults, and automated EHR clinical charting.
The Challenge
Chronic patient monitoring at scale.
Healthcare clinics faced severe staffing constraints managing thousands of chronic hypertension and diabetes patients living in rural communities.
Patients struggled with complex apps, while clinicians were overwhelmed with manual phone check-ins and unverified self-reported vitals.
The Solution
Automated Bluetooth telemetry.
Wadecheryl created a simple mobile app that pairs instantly with cellular and Bluetooth medical devices. When a patient takes their blood pressure or glucose, readings automatically sync into an encrypted cloud pipeline.
AI anomaly detectors alert on-call clinicians only when biometric thresholds breach safe margins, triggering an automated video consultation.
Technical Implementation
How the real-time telemetry pipeline was engineered.
Chronic patient monitoring requires continuous reliability without draining device batteries or overwhelming clinical triage teams with false positives.
Wadecheryl developed a specialized edge-synchronization protocol in React Native. Vital readings from Bluetooth LE hardware are buffered locally in an encrypted SQLite store and transmitted via TLS 1.3 to AWS Lambda ingestion endpoints only when a stable connection is verified.
BLE connection intervals throttled to conserve peripheral battery life up to 180 days on standard lithium coin cells.
Rule engines evaluate systolic/diastolic thresholds, alerting on-duty nurses via Twilio SMS and push alerts within 3 seconds of abnormal vitals.
Pre-formatted clinical notes automatically mapped to ICD-10 and CPT billing codes (99453, 99454, 99457) for maximum reimbursement.
