Educational arithmetic game
Math4Kids
A fast, child-friendly arithmetic game where learners choose operations and difficulty, race the clock, receive immediate feedback, and can submit a score to a protected leaderboard.
The brief
A product problem worth solving.
Make repeated arithmetic practice feel playful and focused, while giving the product a trustworthy score flow that can support public competition without exposing it to abuse.
The work
Built as a system, not just a surface.
I rebuilt Math4Kids with Next.js, React, TypeScript, and a focused game loop: choose an operation and difficulty, solve timed problems, and receive clear visual feedback. The current version adds a Cloudflare Pages deployment, D1-backed high scores, short-lived signed score sessions, and Turnstile protection around score submission.
The result
A live, useful product.
A live educational product and public repository that demonstrates product thinking across interaction design and the operational details behind a small public game: fast feedback, safe score submission, and a deployable serverless foundation.
