Budget: Recommended by industry experts

Time to start: As soon as possible

Project description:
"The back-end is finished and the current PyQt6 interface already contains every screen, widget and option I need. What’s missing is rock-solid stability and the seamless merge of two separate data feeds into that existing front end.

Here is the situation

• I can provide the full code base plus notes on the two independent data sources.
• Freezes occur during long-running sessions and the window sometimes refuses to shut down. I have already checked for obvious coding errors, so the next step is a deeper event-loop / thread review.
• Some buttons intermittently stop responding; the look and feel, however, must stay exactly as it is.

What I need from you (1–2-day turnaround expected)

1. Integrate both data sources so the information flows in real time without blocking the UI.
2. Eliminate freezes and guarantee a clean, reliable shutdown.
3. Make every existing button consistently responsive.
4. Supply the updated, well-commented code so I can run immediate tests in a live environment.

Acceptance will be based on a stress test (no freeze for three continuous hours), full button functionality, and matching the current GUI layout pixel for pixel.

Payment schedule
• 40 % released once the first milestone meets the above expectations and I have reviewed the code.
• Remaining balance released only after successful live-environment testing.

If you are confident with PyQt6 internals, threading, and non-blocking data handling, this should be quick work. I’m ready to start as soon as you are." (client-provided description)
