Internship Project – Social & Q&A Platform

🚀 Visit Link: QueryNest Live

Overview

This project is a full-stack social interaction and Q&A platform developed as part of an internship assignment. The system combines a public social space, StackOverflow-like Q&A features, subscriptions, rewards, security controls, and multi-language support, with multiple business rules and constraints enforced at the application level.

The objective of this project is to demonstrate real-world problem solving, backend business-logic enforcement, authentication and authorization workflows, payment integration, and scalable feature design.
