Fei Li developed and maintained core content ingestion, metadata extraction, and plugin management features for the lockss-daemon repository, enabling robust archival workflows across diverse publishers. Leveraging Java and XML, Fei engineered new source plugins, enhanced HTML and BibTeX parsing, and implemented resilient error handling for HTTP and encoding issues. Their work included refactoring plugin architectures, automating archival unit state transitions, and integrating API-driven crawl seeds to expand coverage. By introducing volume-based filtering, regular expressions, and logging improvements, Fei improved data quality, reduced manual intervention, and streamlined deployment. The depth of work reflects strong backend development and system integration expertise.
