I will do api integration, reverse engineer any private api and build a python wrapper


About this gig
You need to talk to an API that was never meant to be talked to? No documentation, no SDK, no support ticket that will ever be answered?
That is most of what I do. Working out how a system behaves from the outside: the requests it expects, how it signs them, how sessions and tokens refresh, and where the rate limits sit. Then building something that talks to it reliably, every day, with nobody watching.
WHAT I BUILD
- A clean client for an undocumented or private api, in Python or TypeScript
- Browser automation with Camoufox/Patchright there is no api to call at all
- Retries, backoff and token refresh, so it survives the service changing its mind
- Scheduled runs, logging, and an alert when something breaks
- Your data where you need it: database, sheet, webhook or your own api
Send me the service and what you need out of it. Within a day you will know whether this is a two day job or a two week one.

FAQ
The service has no API at all. Can you still help?
Almost always. A web interface has to talk to something, and that something is usually a private api. The first thing I try is to call it exactly the way the site itself does: same requests, same signing, same session. That is faster, cheaper to run and far more stable than driving a browser
Do you do plain web scraping too?
Yes, and often it is the cheaper answer. If the data sits on public pages and nobody needs to log in, that is a smaller job than a full api client and I price it that way.
What happens when they change something?
Everything I build fails loudly rather than silently. You get an alert, not a quiet gap in your data. Adapting to a change is usually an hour of work, and after handover you can do it yourself or send it to me.
How do I know the job is possible before I pay?
A quick look is free: send the service and within a day I will say if it looks straightforward or clearly impossible. Between those sits real investigation, and that is what the Basic package pays for. Some services cannot be reversed at any price, and that answer comes in writing.
