Build
01New API testing work from requirement to production: postman collections that test every endpoint with real scenarios; Contract tests between backend and mobile or partner apps; API documentation that stays in sync with the code.

API testing — contracts your mobile app can rely on.
An API is a promise to every app and partner that uses it. I document APIs, build Postman or Hoppscotch collections that test every endpoint, and add contract tests so a backend change cannot silently break the mobile app.

01 — What I do with API testing
build, fix, upgrade, audit
Fix and maintain
02The usual problems in existing API testing systems: endpoints that changed without telling the app team, undocumented APIs, and bugs found by partners.
Upgrade and migrate
03Word documents to OpenAPI specs, manual Postman clicks to automated runs in CI.
Audit and advise
04A code, security, performance and SEO audit of your API testing system, with a written plan you can act on with or without me.

what people usually ask for
API testing work
that actually gets ordered.
Three shapes most API testing engagements take. Yours may be a fourth; describe it and I will tell you honestly whether it fits.
- Postman collections that test every endpoint with real scenarios
- Contract tests between backend and mobile or partner apps
- API documentation that stays in sync with the code
04 — Questions
about API testing work
Can you document an API that has no docs?
Yes. I reverse-engineer it from the code and traffic, write an OpenAPI spec, and generate readable documentation from it.
What is a contract test?
A test that checks the API still returns exactly what the app expects. It fails before the app does.
How is API testing work priced?
A fixed price for a defined scope, or hourly from $10 depending on the stack, always with a written estimate before any work starts.
How do we start?
Send a short description of what exists and what you need. You get a reply within one working day with questions, then a scope or an estimate.
