PulseGuard RPM
A remote patient monitoring app that connects wearable devices to clinical dashboards, enabling care teams to intervene early and reduce hospital readmissions by 28%.
Project Overview
PulseGuard RPM was developed for a healthcare network that wanted to extend post-discharge monitoring to patients with chronic conditions. Existing remote monitoring tools were clunky, required separate portals for patients and clinicians, and lacked the intelligence to distinguish genuine health deterioration from normal physiological variation.
We built a cross-platform mobile application for patients paired with a clinical web dashboard for care teams. The system collects vitals from consumer wearables and Bluetooth medical devices, applies on-device triage algorithms, and delivers actionable alerts to clinicians — with all data encrypted end-to-end and compliant with healthcare data regulations.
Technical Architecture
The patient-facing app is built with React Native and Expo in TypeScript, delivering a single codebase that runs natively on both iOS and Android. Expo's managed workflow handles over-the-air updates, allowing us to ship critical patches without app store review delays — essential in a healthcare context where regulatory fixes cannot wait.
On-device health triage uses a TensorFlow Lite model that analyses incoming vitals streams (heart rate, blood pressure, SpO2, activity) and flags anomalies in real time. The model runs locally on the patient's phone, ensuring alerts are generated even without network connectivity and reducing unnecessary data transmission.
Firebase powers push notifications and real-time data synchronisation between the patient app and clinical dashboard. When the TensorFlow model detects a concerning pattern, Firebase Cloud Messaging delivers a priority alert to the assigned care team within seconds.
The clinical dashboard is a Next.js application backed by Supabase and PostgreSQL, with GraphQL providing flexible queries for patient timelines, cohort analytics, and alert history. Supabase's row-level security enforces role-based access — nurses see their assigned patients, physicians see their department, administrators see aggregate metrics.
All infrastructure runs on Google Cloud provisioned with Terraform, with data residency configured per regional requirements. Audit logging, encryption at rest, and automated compliance reporting are baked into the platform from day one.
