Android App Stability & Push Notification Prioritization (Healthcare IoT Project)

Job ID: 39706362

Budget: $250 – $750 USD

Context:
Very exciting and impactful healthcare PaaS/SaaS IoT startup with production units already live.

Challenge:
Mobile app is experiencing FCM push notification prioritization issues and broader instability across select android versions.

Note:
The goal is to identify the right developer for a long-term, ground-floor engagement.

HL Tech Stack:
Android (Java/Kotlin with Reactive components)
Firebase Cloud Messaging (FCM) for push notifications
Backend Web Application
Azure backend integration


Priorities:
-Optimize Firebase push notification reliability (delivery, prioritization, and consistency across states).
- Stabilize the app across Android versions/builds for smoother performance.


The ideal partner:
- Proven Android app expertise in IoT contexts, especially where devices connect into cloud + mobile workflows.
- Strong experience with Firebase Cloud Messaging (FCM) — specifically handling prioritization, throttling, and reliable delivery across Android versions and device states.
- Solid grasp of authentication flows (token refresh, session handling) and alignment with Azure-based backend APIs.
- Practical knowledge of Reactive programming (RxJava / Kotlin coroutines) for asynchronous event handling.
- Ability to troubleshoot integration points between the mobile app, backend web app, and cloud infrastructure.
- Ideal fit is a developer with a passion for healthcare, ready to dive in immediately, and motivated by the chance to scale an innovative value-based care solution.
