Developed and integrated the Docling Document Parser into the langchain4j/langchain4j repository, enabling advanced document processing features such as OCR, table extraction, and layout analysis for enterprise workflows. Leveraged Java and the docling-java client to implement a configurable DocumentParser interface, supporting base64 encoding for API transmission and metadata extraction. Established a robust unit testing suite with 20 passing tests and prepared an integration test framework to ensure reliability. Comprehensive JavaDoc documentation was provided, and the code was structured for clear review. This work automated document ingestion and extraction, reducing manual data entry and accelerating processing for enterprise applications.
