Grade 12 student, open-source developer, and competitive programmer in Shanghai
I build tools around real problems in competitive programming and developer workflows. My current focus is CPH-NG, alongside OI training, modern web systems, and a growing Rust practice.
 A competitive-programming workflow for VS Code: sample retrieval, local judging, special judging, stress testing, and multi-platform submission. |  A browser userscript that improves problem solving, discussions, and everyday use on XMOJ. Ongoing development lives in the XMOJ-Script-dev organization. |
