SparkleQuiz

A solo and multiplayer quiz app, playable on the web and published on the App Store and Google Play.

Context

SparkleQuiz is my own business: I have been designing, building and running it on my own since 2025. You can play solo, with a progression system, or with others in rooms synchronised in real time. Players create their own quizzes, add friends and track their statistics. The app is free, playable in the browser and available on both mobile stores.

My role

Founder and sole developer: design, back end, front end, mobile apps, infrastructure and store releases.

What I did

Symfony and MySQL back end, Vue 3 and Tailwind front end, with real-time synchronisation of multiplayer games over the Mercure protocol.
iOS and Android apps built with Capacitor from the same codebase, and published on the App Store and Google Play.
A full progression system: levels, experience, daily quests, 68 achievements and 4 leaderboards synced with Game Center.
Eight continuous integration and delivery pipelines on GitHub Actions, including the Docker production deployment and store listing updates.
End-to-end tests with Playwright on the web and Maestro on mobile, static analysis with PHPStan, performance audits with Lighthouse.
Over 4,000 commits: the product is live and keeps evolving every week.
