This is a running log of my #100日チャレンジ. The goal: to build or create something every single day. It doesn't have to be big – just something that keeps momentum alive.
Day 1
For Day 1, I started building a to-do list app that works with ChatGPT. The idea is simple: you type in what you need to do, and it helps you figure out what to tackle first. I’ve always struggled with knowing what’s “most important” when everything feels urgent — so I thought, why not offload some of that stress to AI?
Day 2
Today I made a game called CodeTrace — a speedrun challenge where you’re given code snippets in JavaScript or Python, and you have to quickly guess the output.
It tracks your accuracy and reveals your coding strengths by category. This was inspired by coding assessment stress and wanting a more playful way to practice under pressure.
Day 3
Today I built a full-featured Tutor Management App using React and Tailwind CSS. The app includes login, dashboards, session scheduling, volunteer tracking, and more — all routed with React Router and designed for scalability. I also wrote a full
README.md
with a GIF preview and started organizing my codebase into clean folders like pages
, assets
, and contexts
