### Student Organizations * 2017–2019, Student Association for Algorithms and Programming, Tsinghua CS — Competition Committee Member, Committee Head, Vice President (Competitions) * 2016–2017, Student Science Association, Tsinghua CS — Intelligent Agents Division Member ## Projects ### Customizable High-Efficiency Memory–File Mapping on Linux2018–2019 Undergraduate thesis project. Built a user-space memory–file mapping runtime on Linux using the `userfaultfd` system call to overcome mmap limitations (write-back policies, unified page management, fixed swap granularity). Achieved up to 25% speedup over mmap on sequential workloads and 23–84% end-to-end improvements on real applications. ### JudgeDuck OS [Repository](https://github.com/JudgeDuck/JudgeDuck-OS), [Live Demo](https://duck.ac/)2018 Operating system designed for precise and stable measurement of program runtime and memory usage, delivering at least 5× higher stability than Linux for programming contests. Powers the Judge Duck Online OJ. I contributed to the core design and early implementation. ## Miscellaneous * Piano: Central Conservatory of Music Amateur Level 10 *Last updated on 13 Nov 2025.*
