I will professionally test your REST APIs using Postman and Swagger/OpenAPI and provide clear, actionable test results. I can test GET, POST, PUT and DELETE endpoints, request and response validation, HTTP status codes, authentication and JWT, positive and negative scenarios, input validation, edge cases, error handling, and Swagger/OpenAPI documentation. I will identify API bugs and issues and provide a clear report with test findings and recommendations. I have hands-on experience with REST APIs, Java, Spring Boot, Postman, Swagger and backend API development. I focus on systematic testing, accurate validation, and easy-to-understand reporting so you can identify issues before deployment.
