I help teams validate endpoints, catch edge cases, and ensure data integrity before bugs make it downstream into your frontend or third-party integrations.

Using tools like Postman and structured test case design, I thoroughly test your API's functionality, error handling, and edge cases — giving you confidence that your backend behaves exactly as expected under real-world conditions.

Functional Testing — Validating endpoints against API specs/documentation (Swagger/OpenAPI)

Request/Response Validation — Checking status codes, payloads, headers, and response schemas

Negative & Edge Case Testing — Invalid inputs, missing fields, boundary values, and unexpected data types

Authentication & Authorization Testing — Token validation, session handling, role-based access checks

Error Handling Verification — Ensuring meaningful, consistent error responses across failure scenarios

Integration Testing — Validating data flow between multiple services/endpoints

Regression Testing — Re-verifying existing endpoints after updates or new deployments

Data Validation — Cross-checking API responses against database records for accuracy

Bug Reporting & Documentation — Clear, reproducible reports with request/response logs via JIRA, TestRail, or your preferred tool
