I will write api documentation, openapi swagger spec, developer guides and sdk docs
Technical documentation and data automation for software teams
About this Gig
Scrivimi pure in italiano.
Most API documentation is written by someone who cannot read the code. That is why it goes stale in three weeks, and why your users still open tickets asking what the error codes mean.
I am a software engineer. Send me the repository, the Postman collection or the route file - I read it myself and write documentation that matches what the service actually does.
WHAT YOU GET
- Every endpoint: method, path, auth, parameters, request and response
- Real error responses, with what causes them and what to do about it
- One working example per endpoint, in curl and in a language of your choice
- A valid OpenAPI 3 file, so the docs can be regenerated after you change the code
- A published docs site on Redoc, Swagger UI or Mintlify (Premium)
REST, GraphQL, webhooks and SDKs. I never need your production keys.
If your API has naming or error handling problems, I will say so before writing. Documenting a confusing API only makes the confusion official.

FAQ
What do you need to document my API?
Any one of these works: a repository, a Postman collection, a GraphQL schema, an existing OpenAPI file, or a sandbox key. If you have none of them, a screen share where you walk me through the calls is enough to start.
Do you publish the docs, or just hand me files?
Both are possible. Basic and Reference are delivered as Markdown plus an OpenAPI file you host yourself. Full Docs includes a working documentation site, built with a static generator, ready to deploy on your own domain.
Will you keep the docs updated when the API changes?
Yes, as a separate smaller order. Send me the changelog or the diff and I update the affected sections. Because you keep the source files, your own team can also maintain them without me.
