I will test your rest API and find the failures that break your product
Senior QA Automation Engineer and Full Stack Developer NET React
About this Gig
An AI can tell you what an API "should" return. I test what YOURS actually
does on your real endpoints and tell you exactly where it breaks, fails
validation, or leaks data it shouldn't.
I'm a Senior QA Engineer with 9 years in software. I test REST APIs against
live backends not from a generated checklist, but by hitting your endpoints
and verifying the real behavior.
WHAT YOU GET:
- Real testing of your endpoints (GET, POST, PUT, DELETE) verified
- Request/response, status code & data-consistency validation
- Authentication & authorization checks (can the wrong user get in?)
- Error handling & edge-case testing
- Clear report: severity, findings, exact reproduction steps
- Postman collection on request
WHY A HUMAN, NOT JUST AI:
- - I use AI to build coverage fast then run and verify every case myself
- - A developer background: I know WHY an endpoint fails, not just that it does
- - Accountability on what matters: auth, data integrity, security
A broken auth check can cost you customers or expose you. Send your API
docs or Swagger link and let's verify it properly.

FAQ
What do you need from me to start?
Your API documentation or Swagger/Postman link, the base URL, and any test credentials or API keys needed. A short note on what matters most helps too.
What does the report look like?
A clear document listing each issue with its severity, endpoint, request/response details, steps to reproduce, and expected vs. actual result — ready for your developers to act on.
Do you provide a Postman collection?
Yes — included in Standard and Premium, and available on request for Basic.
Do you fix the API issues too?
This gig is testing and reporting (finding the issues). I can advise on fixes, but development is separate — message me if you need that.
