Developed a streaming JSON Lines deserialization API for the heremaps/xyz-hub repository, enabling incremental and stream-friendly processing of large JSONL datasets. The solution introduced deserialization from input streams into MappingIterators, supporting efficient memory usage and scalable data handling. The work emphasized code clarity through a targeted API rename and included comprehensive unit tests to validate streaming behavior and performance. Leveraging Java and JSON processing skills, the developer also addressed build integrity by implementing a signing-related fix. The approach demonstrated a focus on maintainable API design, robust refactoring, and clear documentation, resulting in a well-tested and production-ready feature addition.
