Liheng contributed to the apache/doris and apache/doris-website repositories by developing a new Ingestion Load Feature for Apache Doris, enabling automated, scalable data onboarding through refactored load handling and new APIs. Leveraging C++ and Java, Liheng integrated HDFS support to improve reliability and scalability for diverse data types and table structures. Over subsequent months, Liheng focused on technical documentation, updating and expanding guides for Spark integration, SQL usage, and connector dependencies. These documentation enhancements, written in Markdown, improved developer onboarding and reduced support overhead, demonstrating depth in backend development, data engineering, and technical writing across distributed systems and data pipelines.
