About this Gig
I reverse engineer web and mobile app APIs for businesses that lost their source code, developer or documentation. I map how existing app (web, Android or iOS) talks to its backend and give you a working API reference to rebuild, migrate or extend it.
What you get:
- Full API map: endpoints, auth flow, request and response formats
- OpenAPI/Swagger spec and Postman collection
- Working rebuilt backend, client or integration (Standard and Premium)
- Migration plan away from legacy or vendor-locked systems
- Private report of security weaknesses found
- Full app rebuild
Stack: Node.js, TypeScript, React, plus traffic and app analysis tools (Frida, Charles proxy, and more)
You own everything delivered: code, docs and specs.
Message me before ordering with the app, platform and your goal.

FAQ
What does it mean to reverse engineer an app API?
I observe how your app communicates with its server, then document each endpoint, request and response so the system can be understood, rebuilt or migrated.
Can you analyse any app?
Some apps are harder to analyse than others. I confirm feasibility before you commit to the larger packages.
Who owns the deliverables?
You do, including the documentation, specs and code.
Will you sign an NDA?
Yes, on request.
Do you need source code?
No. That's the point of the service, though having it makes things faster.
Can you copy a competitor's app?
