Android HMI for Coffee Roaster

I'm looking for an experienced Android developer to create a Coffee Roaster HMI (Human-Machine Interface) app.

The primary function of this app is to control roasting parameters. It should also display real-time data including:
- Temperature
- Roasting time
- Fan speed

Additionally, the app needs to support multiple roasting profiles.

Ideal skills and experience:
- Android app development
- Experience with real-time data display
- Familiarity with control systems
- Background in coffee roasting technology is a plus

Please provide examples of similar work and estimate the time required.
