About this Gig
Are you building or maintaining APIs and want to ensure they are reliable, secure, and production-ready?
I'm a professional QA Engineer with real-world experience testing REST and SOAP APIs for SaaS products, startups, and backend systems.

- Authentication (JWT, OAuth, API keys)
- CRUD operations
- Response validation (status codes, schema, data)
- Negative and edge-case scenarios
Tools I use:
- Postman
- Newman (CLI automation)
- Swagger / OpenAPI documentation
- cURL (if required)
What you will receive:
- Detailed API test report
- Bug list with severity and reproduction steps
- Postman collection
- Newman execution report (for automated tests)
- Test summary document
This gig is ideal for:
- SaaS backend teams
- Startup founders
