Month 2025-11 Summary: Prioritized developer experience, documentation quality, and runtime reliability to accelerate feature adoption and reduce maintenance risk. Delivered comprehensive SGLang Scheduler Evolution Documentation Enhancements for the Awesome-ML-SYS-Tutorial repo, detailing the migration from a serial processing model to a CPU/GPU-overlapped design, with author attribution, bilingual versioning, readability improvements, and new resources/links (Zhihu). Fixed a critical async-runtime compatibility issue by updating Event Loop usage to uvloop 0.22.x (get_event_loop -> get_running_loop) in sg lang project, improving stability in asynchronous execution. Overall, these efforts enhanced onboarding, collaboration, and production robustness across both repositories. Technologies/skills demonstrated include Python, asyncio, uvloop, documentation engineering, bilingual content creation, and commit hygiene.
