PROFILE
Alex Yeriemieiev
Alex Eremeev enhanced image upload reliability for the GreenCityMVP21 repository by developing and refactoring a comprehensive suite of unit tests for the ImageValidator component. Using Java, JUnit, and Mockito, Alex focused on validating edge cases such as null inputs and enforcing strict MIME type checks, allowing only PNG, JPEG, and JPG formats while rejecting disallowed or null content types. The work included parameterized tests and improved error handling, resulting in a more maintainable and efficient test suite. These changes increased data integrity, reduced production risk, and demonstrated a methodical approach to backend development and test-driven validation practices.
