Python Expert: Financial WebSocket & Audio Sync (GUI Built)

OVERVIEW:DailyQuotes Inc. is seeking an elite, independent Python developer for immediate contract work to finalize a high-performance desktop market tracking utility.THE CURRENT STATUS:The complete front-end user interface layout, 14-column silver trading grid, custom user check-boxes, text-resizing components, and standard Windows setup wizard installer are 100% completed and structurally stable. You are NOT building this app from scratch. You are inheriting a pre-built visual code shell. A strict corporate Non-Disclosure Agreement (NDA) must be digitally signed before source files are shared.TECHNICAL OBJECTIVES & RE-ARCHITECTURE:Multi-Broker Connection Repair: Take the existing code frame, analyze the background network scripts, strip out legacy sandbox variables, and establish active, flawless multi-threaded data connections to stream real-time data from THREE distinct brokerage services based on user configuration: Alpaca Securities (WebSockets), Charles Schwab (OAuth2/API), and Interactive Brokers (IB API / TWS Gateway integration). The milestone will only be released when the 14 rows display real-time flashing stock quotes on the client’s workstation out of the box.Visual Asset Patch: Modify the compiled application asset properties to change the desktop execution shortcut icon and main window display logo from its current theme color to corporate Green.Audio Engine Sync: Wire the internal text-to-speech engine to track active column variables, ensuring that when the user adjusts the speed intervals and checks the "Speak" boxes, the desktop speakers dictate the tape cleanly without latency or system lag.Legal Intercept Gate: Hardcode an un-bypassable Financial Risk Disclaimer pop-up box that blurs the application frame on initial boot, forcing the user to check a mandatory terms agreement box to unlock the utility.THE RETAINER CONTRACT BONUS:This is a 2-Milestone fixed-price delivery contract budgeted at exactly $1,200.00 total. The exact millisecond the core utility runs smoothly on autopilot, the main contract will close, and DailyQuotes Inc. will immediately issue a recurring, ongoing Monthly Maintenance Retainer of $150.00 per month for a hard cap of 4 hours of on-call technical support per month. If zero hours are used, the full $150.00 is still paid to keep our organization on your active priority client list.REQUIRED EXCELLENCE:Deep mastery of Python, asyncio, low-latency multi-threading, and financial exchange APIs (specifically Alpaca, Schwab API, and IBkr API). Independent specialists only. No agencies.Please reply with your direct availability to begin architectural review this week. Thank you.
