QuizDash is a full-stack trivia

QuizDash is a full-stack trivia quiz app I built end-to-end with Flask and SQLite, from database design through deployment. Players select a category and difficulty level, then race a countdown timer that scales with difficulty — harder questions are worth more points but allow less time to answer. I designed the SQLite schema for questions and scores, built out the backend routes for fetching randomized questions, submitting scores, and aggregating leaderboard rankings via SQL, and implemented session-based authentication for a password-protected admin panel where questions can be added or deleted without touching the database directly.

On the frontend, I used vanilla JavaScript and Jinja2 templates (no framework) to handle the quiz flow, live countdown bar, and a post-quiz review screen showing right vs. wrong answers per question. The layout is fully responsive, adapting from a stacked single-column view on mobile to a side-by-side quiz-and-leaderboard layout on desktop. The app is deployed live on Render with secrets (session key, admin password) managed through environment variables rather than hardcoded in the codebase.
