I will api testing and automation with rest assured, postman jmeter

A broken API means broken apps, failed payments and angry customers. Most teams only test the happy path.

I'm a QA Director with 12+ years testing APIs for banking, wealth management and healthcare platforms, where a wrong response costs real money. I'll make sure your APIs work, fail safely and stay that way.

What I test:

- REST APIs: status codes, response body, schema and headers

- Positive, negative and edge cases (invalid input, missing fields, limits)

- Authentication: OAuth2, JWT, API keys, role-based access

- End-to-end API chains: create, read, update, delete

- Basic performance checks on response times

Tools:

- REST Assured (Java + TestNG/JUnit) automation framework

- Postman collections with Newman for CI

- Karate DSL, if you prefer BDD-style tests

You receive:

- Automated API test suite with clear reports

- Bug report with request/response evidence and severity

- CI/CD integration (GitHub Actions, GitLab, Jenkins)

- README so your team can run and extend it

Send me your Swagger/OpenAPI docs or Postman collection, and I'll reply with a free test plan before you order.
