Hi, there! My name is Nick Chen, also cjyx9. I'm now an undergraduate from JNU, majoring in Comuputer Science and Technology. I'm interested in web security and development. And I ocassionally play CTF games with my schoolmates in team JNSEC. I'm also creating opensource projects on GitHub and contents on my Blog.

I am good at Web in CTF competitions. And here are some CTFs I have participated in:

  • MoeCTF 2025 Rank 36
  • ?CTF 2025 Campus track Rank 3
  • 2025年“羊城杯”网络安全大赛 first blood of web EZ_Signin
  • RCTF 2025 Rank 12 (JNSEC), first blood of misc 514

I've been actively involved in open source communities for several years, and contributed to some well-known projects, including Rin, Astro Docs, etc.

Here are some of my personal projects:

  • Official Website of Animeko

    Fully static website for Animeko, built with Astro within 1 day.

  • Random Elysia

    Cloudflare workers + D1 + Elysia.js + Drizzle ORM template. Using my own OAuth2 implementation for authes and modern backend framework Elysia.js. Front-back separated.

  • NewStar CTF Registration Platform (Frontend)

    Registration system based on Solid.js + Rust, featuring a user-friendly architecture and comprehensive state management.

Beyond coding, I enjoy reading japanese light novels and watching animes. I'm a big fan of 京アニ and 芳文社. Here I'd like to recommend three of my favorite works: ゆるキャン△、 ぼっち・ざ・ろっく and 蟲師。

I'm also a music lover, especially fond of J-Rock/J-Pop, Progressive Metal and Shoegaze Rock. Here's my playlist on NetEase Music
