Five9 Call Tracking & Upsell Program

I'm in need of a Java program designed to operate on the Five9 platform. This program should be able to listen to calls and identify key customer purchases based on specific keywords (like 'radiator', 'condenser').

Key features:
- Upsell suggestions: The program should provide upsell suggestions in a pop up window or as transparent text on the screen.
- Call logging: The program should also log calls for further analysis.

Ideal candidates for this project should have:
- Extensive experience in Java programming.
- Previous work with the Five9 platform would be a significant advantage.
- Skills in creating user-friendly pop-up interfaces.

Please ensure to highlight relevant experience in your bid.
