During December 2024, Charbel focused on enhancing the Android code generation pipeline for the Backbase/openapi-tools repository. He addressed a nuanced issue in the Mustache-based Android templates, ensuring that query parameters with leading underscores were preserved during code generation, which previously led to parameter loss. Charbel also improved the instantiation of MultipartCall for collections such as lists, arrays, and sets, supporting more robust multipart request handling in generated APIs. Leveraging his skills in API development and code generation, Charbel’s targeted bug fix increased the reliability and maintainability of the Android codegen process, though his contributions were limited to bug resolution.
