Thorough QA Engineer Needed: Spring Boot (Java) API Testing via Postman (Code-Review & Documentation Required) -- 2

@Mats100

Hi,I have experience testing Spring Boot REST APIs through detailed manual and Postman-based workflows, including reading Java code to understand validation logic, business rules, edge cases, and failure scenarios before designing test coverage. I can create exhaustive test cases for all 64 endpoints covering positive, negative, boundary, authorization, validation, and regression testing with proper HTTP status verification and structured documentation. I am also experienced in organizing Postman collections, environment files, and maintaining detailed reports with screenshots for every executed request and response, including bug tracking, severity classification, retesting after fixes, and regression validation. My previous documentation formats include Test Case ID, objective, prerequisites, payload, execution steps, expected vs actual results, screenshots, and bug references in a clean and developer-friendly structure. I understand the budget limitation and can work within the mentioned final budget while ensuring complete delivery of testing, reporting, and retesting requirements.

I have 10+ years of experience in Java, Spring Boot, Microservices, REST APIs, and enterprise application development. Unlike a traditional QA tester, I can thoroughly analyze the Spring Boot source code to understand business logic, validations, exception handling, and hidden edge cases before creating test scenarios. I have extensive experience testing REST APIs using Postman, including positive, negative, boundary, security, and regression testing. I can deliver a well-structured Postman collection, detailed test case documentation with screenshots for every test execution, comprehensive bug reports with reproduction steps, and complete retesting after bug fixes. My strong Java development background enables me to identify issues that are often missed by testers who rely only on API specifications. I am committed to providing exhaustive test coverage across all 64 endpoints and delivering high-quality documentation within the agreed timeline and budget.
