Nick Chen

My name is Nick Chen, also known as cjyx9. I am an undergraduate majoring in Computer Science at Jiangnan University, with a strong interest in web security and web development. I occasionally play CTFs with r3kapig and JNSEC, and I share my open-source projects on GitHub.

I'm currently learning ヲタ芸 with Team MEGA.

Here are some of my competition results:

• Ali CTF 2026 — 22nd place (competing solo under the team name JNSEC)
• RCTF 2025 — 12th place (as a member of JNSEC; first blood on Misc 514 and third blood on Web Author)
• ...

I'm actively involved in open-source communities. Here are some of my personal projects:

• 100 Days

  Collection of my recreational coding pieces

• 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.

• Misuzu

  Full featured auto solve agent for CTF challenges.

Beyond coding, I enjoy reading Japanese light novels and watching anime. I'm a big fan of 京アニ and 芳文社. Here are 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. Here's one of my playlists on NetEase Music
