Developed a robust CSV reader for the fungover/breeze repository, focusing on scalable data ingestion and efficient memory usage. The solution leveraged Java, utilizing the Builder Pattern and Java Streams to enable configurable parsing, including custom delimiters, quote handling, and empty-line skipping. The reader supported reading from strings, streams, and files, and provided object mapping for seamless integration with downstream systems. Emphasis was placed on reliability, with extensive unit testing and edge-case coverage to ensure consistent behavior across diverse CSV formats. This work delivered a core ingestion feature, enhancing the repository’s ability to process large datasets with flexible, maintainable code.
