Mobile Engineering Healthcare
Telehealth Mobile Platform
Offline-first mobile application for remote patient monitoring in low-bandwidth areas.
The Outcome
100% data integrity in field tests. App load time decreased from 8s to 0.8s.
Tech Stack
React Native WatermelonDB Node.js TypeScript
Technical Bottlenecks
Patient data was being lost in rural areas due to poor connectivity. The existing web-view app was sluggish and unoptimized for older devices.
The Solution Design
High-level System Design
We rebuilt the core in React Native with WatermelonDB for local-first persistence. A custom sync engine queues requests and processes them when connectivity is restored.
Engineering Rigor
- Implemented automated CI/CD pipelines ensuring 99.9% uptime.
- Comprehensive unit and integration testing coverage using standard libraries.
- Full documentation of API endpoints and system dependencies.
