Scouting report

Built jieba, the 35k★ Chinese NLP standard

assessed from open-source footprint

Principal
63signal

Andy is the primary author of jieba (34,986★), the de-facto Chinese word-segmentation library used across the Python ecosystem, with 155 merged PRs to his name and 3,141 followers. That single project is a heavyweight credential, though recent GitHub activity is light (4 commits last year) and many older repos are dormant. Ideal for backend/NLP teams who value a builder with genuine open-source reach.
