Downloadable Desktop Trading Application Development

I’m looking to build a downloadable desktop trading platform and would like to get a quote for the project. Here’s an overview of what I need:

Project Goal
The end goal is a downloadable desktop application that users can install and run locally. It will:

Run Trading Strategies: Execute Python-based trading strategies (I already have the Python scripts).

Integrate with IBKR: Connect to Interactive Brokers’ TWS/Gateway (users will install this separately).

Offline Functionality: Work without an internet connection after installation.

Key Features
Frontend (UI):

I have the design and code already for this
(https://nts-algo-interface.vercel.app/)

Allow users to:

Select and run trading strategies.

Input configuration settings..

View logs/output in real-time.

Backend (Python):

Refactor existing Python trading scripts into a modular system.

Expose functionality to the frontend via a local API (e.g., FastAPI/Flask).

Ensure seamless communication between the Electron frontend and Python backend.

Packaging:

Package the Python backend and Electron frontend into a single downloadable file.

Create installers for Windows, macOS, and Linux.

Security:

Obfuscate Python code to protect intellectual property.

Encrypt sensitive configuration files.

What I’ll Handle
Payment System: I’ll integrate Stripe for license purchases.

License Key Generation: I’ll handle the logic for generating and validating license keys.

What I Need from You
A downloadable desktop app that meets the above requirements.

Clear documentation for setting up and running the app.

Recommendations for the best approach to achieve the goal (e.g., tools, architecture).
