Born in Shanghai · CS & AI · Competitive Programming

I'm currently a university student, studying Computer Science and Artificial Intelligence. I'm highly motivated to participate in CS and AI-related programs, internships, or collaborative projects. I'm happy to help where I can, and I'm also open to taking on paid projects. Setups: Computer: I run CachyOS (previously Arch Linux) with the niri window manager. I have a desktop PC with dual monitors and a laptop with a large screen. Total storage capacity is approximately 20 TB. Phone and watch: I use a Google Pixel 10 Pro (previously Pixel 9 Pro) as my daily driver, a Google Pixel Watch 4, and a Google Pixel Buds Pro 2. I genuinely enjoy all of them. Alright, recently I am considering the Apple ecosystem. Skills: Languages: Native speaker of Simplified Chinese (used only in daily life). English proficiency is at C1 level, with stronger performance in CS/AI technical contexts. I can also read most Traditional Chinese, and understand Shanghainese. Competitive Programming: Passionate about algorithms and competitive programming. I won awards in high school, currently create algorithm explanation videos on YouTube, practice regularly on Codeforces, and plan to compete in XCPC. AI: I closely follow the latest AI models and evaluate them across different domains. I have intermediate knowledge of machine learning algorithms and model training, and remain very interested in this field. Web Development: Extensive experience in front-end development. I also have some back-end knowledge and am currently deepening my understanding of networking. Channels (YouTube & Bilibili): NailFec: Personal channel sharing experiences and thoughts. NailFec Algo: Clear introductions to competitive programming algorithms. NailFec Linux: Recommendations of useful tools and efficient Linux techniques. Projects (GitHub): Liminal: A GUI tool for configuring the Limine bootloader with real-time preview. RubricFlow: A web platform that helps Shanghai high-school English teachers use AI to grade open-ended responses (translations, summaries, essays). It assigns scores and generates analytical reports based on specific requirements. Ledger: A money tracker program, with well-designed IOS, Android and website versions.

Experience

I became interested in computers in middle school, mainly about UI/UX design, before I had a machine of my own. In the first month of high school, I learned lots of algorithms after class, won a prize, and then kept going on my own. Algorithms and theory are still what I care about most. There is a long way left, and I learn quickly.

I like building as well. I taught myself operating systems, computer networks, front-end, back-end, GUI development, etc. I use CachyOS day to day, publish my projects, and stay in the open-source community. I also study machine learning, training, and agents, including a summer at NYU Shanghai taught entirely in English.

  1. CSP-S and NOIP. First prize in CSP-S round one, second prize in round two, and third prize in NOIP.

  2. Algorithms paper. Presented "Data Structure Algorithms for Large-Scale Queries."

  3. NYU Shanghai. First place in the NYU Shanghai AI Summer Program.

  4. Duke Kunshan University. Ranked 82nd among Shanghai finalists in Duke Kunshan University's comprehensive evaluation.
