SQA Engineer and Software Testing Expert
About this Gig
Need your APIs tested and validated before launch? I've got you covered.
I'm an SQA Engineer with 4+ years of experience in API testing for production systems. I use Postman, REST Assured, Swagger, and SoapUI to catch bugs before they reach your users.
Broken APIs mean angry users and lost revenue let's make sure that doesn't happen.
WHAT I WILL TEST FOR YOU:
- Status codes (200, 400, 401, 404, 500 no surprises)
- Response time is your API fast enough?
- Response data correct format, no missing fields
- Authentication API keys, JWT tokens, OAuth
- Error handling does it fail gracefully?
- Edge cases what happens with bad inputs?
TOOLS I USE:
- Postman (manual + collections)
- REST Assured
- Swagger/OpenAPI (documentation review)
- SoapUI (SOAP APIs)
- JSON validators
- Browser DevTools for debugging
WHAT YOU GET (based on package):
- Detailed bug report with severity levels (High/Medium/Low)
- Screenshots of every bug found
- Postman collection of all tests performed
- Recommendations to fix each issue
- Re-testing after fixes (included in revision)
IMPORTANT NOTES:
- Source code? Not needed I just need your endpoints.
- Private/confidential APIs? Happy to sign an NDA.

FAQ
Do I need to share my source code?
No, I only need your API endpoints (URLs) and any authentication details (API keys, tokens). Your source code stays private.
What if you miss a bug?
I test thoroughly, but if I miss something, message me within 3 days of delivery and I'll re-test for free.
Can you test private/local APIs?
Yes, if they're accessible via public URL (like staging server) or we can arrange a screen share session.
Can you sign an NDA?
Absolutely. Send me your NDA and I'll sign it before starting work.
What's the difference between manual and automated testing?
Manual testing is what I do for all packages. Automation (in Premium) means I create a Postman collection you can run yourself anytime.
