Client's Testimonial

Developers.dev was more than a vendor; they were the critical engineering partner we needed to bring this vision to life. Their expertise in HIPAA, BLE connectivity, and building mission-critical software was evident from day one. They delivered a world-class application that is now a core part of our market-leading solution.

VP of Digital Innovation, MedStream Technologies

Client Introduction

A leading US-based medical device manufacturer (> $100M ARR) specializing in cardiac monitoring solutions. They needed to develop a secure, reliable, and FDA-compliant watchOS and Wear OS application to pair with their new continuous ECG monitoring patch. The goal was to provide patients with a user-friendly interface and transmit critical data to clinicians in real-time.

Problem

The client's hardware was best-in-class, but they lacked the in-house expertise to build a sophisticated, cross-platform wearable application that could meet the stringent demands of the healthcare industry for security, reliability, and user experience.

Key Challenges

HIPAA Compliance

Ensuring all data transmission and storage met strict HIPAA security and privacy rules.

BLE Reliability

Establishing a rock-solid, power-efficient Bluetooth Low Energy connection for continuous, uninterrupted data streaming.

Cross-Platform Parity

Delivering a consistent and intuitive user experience across both Apple Watch and Wear OS devices.

Data Integrity

Guaranteed zero data loss from the sensor to the clinician's dashboard.

Our Solution

We assembled a dedicated "Healthcare Interoperability Pod" consisting of a project manager, two senior mobile developers (one Swift, one Kotlin), a BLE expert, a QA automation engineer, and a UI/UX designer with experience in medical applications.

🔒 Secure Architecture

We designed a HIPAA-compliant cloud backend on AWS, using encryption for all data at rest and in transit.

🔗 Robust Connectivity Protocol

We developed a custom BLE data transfer protocol with error checking and data packet re-transmission to ensure reliability.

🎨 Unified Design System

Our UI/UX team created a design system that provided a native feel on each platform while maintaining brand consistency and usability for an older patient demographic.

🧠 AI-Powered Alerts

We integrated a lightweight, on-device AI model to detect potential anomalies in the ECG data, triggering immediate alerts to both the patient and the care team.

Implementation and Execution

Discovery Sprint

Conducted a 2-week discovery sprint to finalize the technical architecture and user flows.

Agile Sprints

Operated in 2-week agile sprints with daily stand-ups and bi-weekly demos.

Kotlin Multiplatform

Utilized Kotlin Multiplatform to share the core data processing logic between the iOS and Android apps, reducing development time by 20%.

Automated Testing

Built a comprehensive automated testing suite covering unit, integration, and UI tests.

Real-World Testing

Performed extensive real-world testing with a pilot group of users to fine-tune the BLE connection and battery performance.

FDA Documentation Support

Provided complete technical documentation to support the client's FDA 510(k) submission.

Positive Outcome

✅ Successful FDA Clearance

The client successfully received FDA clearance for their device, with our software documentation being a key component of the submission.

⬆️ 99.9% Data Uptime

The application achieved near-perfect data transmission reliability in clinical trials.

👨‍👩‍👧‍👦 High Patient Adoption

The intuitive UI led to a 95% patient adherence rate in the initial rollout.

📉 Reduced Hospital Readmissions

Early data from the launch cohort showed a 10% reduction in hospital readmissions for patients using the device.
