QuizzApp

Community quiz platform with a moderation workflow

Overview

QuizzApp lets users create two kinds of quizzes: knowledge quizzes that are scored, and fun quizzes that work like polls. Every quiz goes through admin moderation before it is published.

The problem

User-generated quizzes need moderation — including edits to quizzes that are already live — without exposing unreviewed content.

Key features

• Knowledge quizzes with scoring and fun quizzes with one vote per user per question
• Moderation states: pending, approved, rejected and pending update
• Editing a live quiz creates a draft; the original stays live until the draft is approved
• Image upload for quizzes and answer options
• Admin analytics and user management; user stats and a leaderboard
• Animated results page and mobile-friendly navigation

Architecture

• .NET 10 Web API with EF Core on PostgreSQL
• JWT authentication with role claims and an admin-only policy
• Next.js 16 App Router frontend with Tailwind CSS and Zustand

Technical challenges

• Versioned moderation of live content through parent/draft quizzes
• Two result models in one engine: scoring and vote tallies
