About this gig
Mobile app development for IoT and sensor-based hardware products.
Built with .NET MAUI cross-platform C#, runs on Android and iOS from a single codebase.
Background in Mechanical Engineering and .NET development. I can help with hardware setup, sensor integration, mobile app, or the full stack from device to cloud.
Supported connection types: Bluetooth, WiFi, USB, cloud APIs.
Available extensions depending on package:
- Azure backend with REST API
- FHIR integration for healthcare projects
- User authentication
- Measurement history and local storage
- Data export
- Multi-device cloud sync

FAQ
What hardware connection types do you support?
Bluetooth (BLE and Classic), WiFi, USB. If your device uses a different protocol, message me before ordering and I'll let you know if it's possible.
Will the app run on both Android and iOS?
Yes — .NET MAUI uses a single C# codebase that compiles to both platforms. Android testing is included in all packages. iOS builds require a Mac environment, which I can arrange.
Do I need an Azure account for the backend?
Only for Standard and Premium packages where cloud features are included. Basic runs entirely with local storage on the device. For Standard and Premium I'll help you set up Azure if you don't have it already.
What if I don't have my hardware ready yet?
No problem. I can build the app with simulated sensor data first, so you can test the UI and visualization before your hardware is finalized.
Can you sign an NDA?
Yes. I understand IoT and medical projects often involve sensitive information. Happy to sign an NDA before any project discussion.
