About this Gig
Hi, I'm Shemaka a Senior QA Engineer with 5+ years of experience in API testing and automation. I've tested enterprise APIs for real products using Postman, Karate, and REST-assured.
What I do
I test your REST APIs end-to-end making sure every endpoint returns the right data, handles errors correctly, and doesn't break under real-world conditions. In simple terms: I make sure your backend works exactly the way your frontend expects it to.
How I do it
- Test every endpoint for correct responses and status codes
- Validate request payloads, JSON schemas, and headers
- Test authentication flows OAuth, JWT, API keys
- Run positive, negative, and edge case scenarios
- Deliver a clear bug report with exact steps to reproduce
Why choose me
Most QA testers only check if an API returns 200 OK I go deeper. I test what happens when it doesn't. With real-world experience on enterprise and startup products, I catch the edge cases that break your app in production. You get a detailed, developer-ready report that makes fixing issues fast and easy.

FAQ
What do I need to share to get started?
Just share your API documentation, Postman collection, Swagger link, or a list of endpoints with their expected behavior. The more context you provide, the more thorough my testing will be.
Do you test private or authenticated APIs?
Yes. I can test APIs that require authentication including OAuth2, JWT tokens, and API keys. Just provide a test environment access token or sandbox credentials and never share production keys.
What's the difference between Basic and Standard?
Basic covers a quick health check of your core endpoints — great if you need a fast validation before a release. Standard is a complete test covering authentication, edge cases, schema validation, and a detailed bug report. If you're unsure, Standard is the right choice for most projects.
Will you test my API in production or a staging environment?
I always recommend testing in a staging or sandbox environment — never production. This avoids any risk of affecting real users or data. If you only have a production environment, just let me know and we can discuss the safest approach.
What will the bug report include?
Every issue is documented with the endpoint URL, request used, actual response received, expected response, severity level, and exact steps to reproduce. Your developer can fix each issue directly from the report without needing to guess anything.
