Hi, there! My name is Nick Chen, also cjyx9. I'm now a freshman from JNU, majoring in Comuputer Science and Technology. I'm interested in web security and development. And I ocassionally hack with my school team JNSEC and Arr3stY0u in CTF games. Creating opensource projects on GitHub and contents on my Blog. Currently, I'm playing codes on my 100 Days Challenge.

Here are some of 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, third blood of web Author

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.

  • NewStar CTF Registration Platform (Frontend)

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

  • 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.

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
