About this gig

I will reverse-engineer JS & Android apps to extract data & APIs.

I help you get data or understand how a website or Android app talks to its server.

If a feature is hidden, or theres no public API, I can reverse-engineer the app or the JavaScript so you can get the data you need for research, testing, or building your own tools.

What I do

  • Read and analyze the app or website code (JavaScript or Android) to find how it requests data.
  • Figure out the network protocol or API endpoints the app uses.
  • Provide a clear report: what the app calls, how to call it, and example requests/responses.
  • Optional: deliver a small script (Node.js / Python) that automatically fetches the data for you.
