I will do API testing using postman or swagger and deliver a detailed test report

Broken APIs break products. I'll test your REST APIs end-to-end and make sure your endpoints behave exactly as expected before they cause issues in production.

I've performed API testing professionally across fintech, trading, AI, and healthcare platforms using Postman and Swagger. I validate request/response structures, status codes, authentication, error handling, and edge cases.

What you get:

Full API endpoint testing (GET, POST, PUT, DELETE, PATCH)

Validation of request/response payloads and status codes

Authentication & authorization testing (Bearer token, API key, etc.)

Edge case & negative testing

Postman collection + detailed test report with pass/fail results

Tools: Postman, Swagger/OpenAPI

I've tested APIs for platforms like a Swiss tax-calculation system, an AI-powered recruitment tool, and an automated trading platform so I handle complex workflows confidently.
