🎯 Quiz Builder

A full-stack Quiz Management Platform built with ASP.NET Core Web API, Angular, and SQL Server, following modern software engineering and clean architecture principles.

📖 Project Overview

Quiz Builder is a full-stack web application that enables users to create, manage, publish, and attempt quizzes through an intuitive web interface.

The project demonstrates end-to-end software engineering practices, including requirement analysis, domain modelling, REST API design, secure authentication, frontend development, and SQL Server integration.

The solution was developed following a structured engineering approach rather than jumping directly into implementation.

📋 Requirement Decomposition and Feature Identification

Business requirements were analysed and decomposed into functional capabilities before implementation.

🗂 Initial Domain Entity Mapping

The application domain was modelled to identify core entities, relationships and database boundaries before implementation.

🔄 Application Workflow and API Design

Application workflows and API interactions were designed before implementation to define user journeys, service responsibilities and communication patterns.

🏗 Solution Architecture

The application follows a layered architecture separating presentation, business logic and data access responsibilities.
