Worked on stabilizing URL handling and enhancing test coverage for the zio/zio-http repository, focusing on the HttpCliApp component. Addressed a critical bug in URL generation by correcting the fold direction within the transformation logic, which improved the accuracy and reliability of endpoint interactions for CLI usage. Expanded the test suite to cover DELETE requests with multiple path parameters, ensuring robust validation and reducing the risk of future regressions. Leveraged Scala for backend and API development, with an emphasis on thorough testing practices. These contributions strengthened the client layer’s reliability and provided a safer foundation for ongoing and future refactoring efforts.
