Worked on stabilizing Android code generation for the Backbase/openapi-tools repository, focusing on improving the reliability of API development workflows. Addressed a bug in the Android template generation process by ensuring that query parameters with leading underscores are preserved, preventing parameter loss during code generation. Enhanced the instantiation of API calls by updating the templates to use MultipartCall for collections such as lists, arrays, and sets, which supports more robust handling of multi-part requests. Utilized Mustache for template logic and applied code generation expertise to reduce the need for manual post-generation edits, resulting in a more maintainable codebase.
