During December 2025, Xu Chen developed two core features for the jxxghp/MoviePilot repository, focusing on backend improvements using Python and data parsing techniques. Xu enhanced the promotional offer mapping system by introducing expanded mappings for upload and download volume factors, allowing users to see more granular and accurate promotional offers. Additionally, Xu updated the Gazelle site parser to support multiple program versions and multilingual pagination, addressing both English and Chinese navigation elements. These changes improved the robustness and localization of data ingestion, reduced manual curation, and expanded international coverage, reflecting a thoughtful approach to backend development and web scraping challenges.
