Therapy device, patient app and doctor CRM as one connected system

Project goal

Client: PulseV, Kazakhstan. Healthtech.

PulseV had therapy devices and no software around them. Patients could not run treatment programmes from a phone. Doctors had no system to prescribe and follow treatment.

Solution

We built the software side of the product:

• A mobile app for iOS and Android on Kotlin and Compose Multiplatform: Bluetooth connection to the device, programme playlists, chat with a doctor and activity history.
• A CRM for doctors on Angular: patient records, prescriptions, a request queue and cover when a doctor is on leave.
• A Kotlin and Spring Boot backend (JHipster) with PostgreSQL and WebSocket.
• ESP32 firmware with its own serial protocol and an OTA partition. Device power is set in the CRM and travels through the backend and the app to the device.
• Six interface languages, CI/CD on GitHub Actions, hosting on Hetzner.

The first version of the CRM took one week.

Results

• 100+ users.
• First stage delivered in 15 days.
• “He responded to every request quickly, made the changes we needed and gave useful advice on improving the features. All tasks were completed well and on time. Every stage was discussed in detail, and as a result we got a fully working product, ready to use.” — Danil Klimov, PulseV. Review on Freelancehunt after the first stage, October 2024, translated from Russian.

Why it matters for you: If you make a medical device, we can build the firmware, the patient app and the clinician tools as one system.
