Works

Projects I built, communities I run, and competitive programming logs worth keeping in one place.

Projects

Web apps, desktop tools, and Rust projects that are public enough to point people to.

2025 - Web Service

A practice helper that randomly picks AtCoder problems from a selected difficulty range. It uses a Rust backend and a Svelte frontend.

2026 Theme

An Astro/Svelte theme for blogs, documentation, and portfolios, with MDX components, search, dark mode, and SEO support.

2024 - Portfolio

This site. I rebuilt it with Astro to keep my profile, technical articles, and daily logs readable over time.

Competitive programming and the surrounding things I keep doing.

2024 - Community

An official competitive programming circle at Wakayama University. It started in December 2024 and focuses on AtCoder and onsite contests.

2024 - Contest

I prefer long-form heuristic contests over short algorithm rounds. As of July 2026, my Heuristic Rating is in the 1600 range.

2026 Contest

I participated as part of team WaSanBon and kept the result and regrets as a log for next year.

Small projects, but they are published on crates.io.

2026 CLI

A Rust task-management CLI for organizing daily work with a little more structure than a plain memo, including dependencies and ordering.

2026 CLI

A tiny Rust CLI that reacts to git typos. It is a small joke project, but it is published on crates.io.
