Hi, I'm malleroid 👋

I'm a developer who enjoys competitive programming and building tools around it.
Right now I'm focusing on open source tools that make it easier to set up and manage competitive programming environments.

What I'm working on

• malleroid/online-judge-toolchain
  A CLI toolchain to help run, test, and organize problems from online judges locally.
  It aims to reduce the friction between “reading the problem” and “running your solution with proper tests”.

• malleroid/atcoder-docker
  Docker-based development environments for AtCoder.
  The goal is to provide a reproducible, language-ready environment so you can start solving problems without spending time on setup.

These projects are still in an early/“growing” stage, but I plan to maintain them for the long term and keep polishing the developer experience.

How your sponsorship helps

GitHub Sponsors will allow me to:

• Secure dedicated time for development and maintenance
• Improve documentation, examples, and onboarding for new users
• Cover costs for CI, testing infrastructure, and other development tools
• Experiment with new ideas like libraries and utilities that build on top of these tools

Even a small monthly sponsorship or a one-time contribution makes a big difference.
It tells me these tools are useful and motivates me to keep improving them 🚀

ありがとうございます — and thank you for considering supporting my work!
