Project description:
"I have already decompiled a mobile game and identified the REST endpoints it uses to report level, score, and other usage stats. What I now need is a small tool or proxy that sits between the game client and the remote service, captures each request, multiplies the key numerical values by 100, then forwards the modified payload so the server records the boosted figures.

Here is the flow I expect:

• Game sends its usual JSON / HTTP request.
• Your middleware (Python mitmproxy script, Node reverse proxy, or a lightweight Android/iOS hook—whatever you prefer) intercepts it.
• Specific fields such as level, score, and play-time counters are read, multiplied by 100, and written back into the request body.
• The altered call is released unchanged in every other respect, so the response arrives as if nothing unusual happened.

I will provide the decompiled code snippets that show the endpoint URIs and sample payloads, plus test accounts for quick verification. Deliverables are:

1. Source code of the interceptor with clear inline comments.
2. A short README explaining how to install, run, and toggle the multiplier.
3. Proof-of-concept video or logs demonstrating an unmodified call versus the 100× version hitting the live server.

Feel free to lean on familiar traffic-manipulation tools—Charles, Fiddler, Burp, mitmproxy, Frida, etc.—as long as the final setup remains portable and easy for me to reproduce on Windows or macOS." (client-provided description)
