DocQuest — Complete EdTech Platform

React NativeNext.jsExpressPostgreSQLGemini AIGCP

01. The Challenge

A coaching business needed a full tech product from scratch — a student-facing mobile app for JEE/NEET practice, an enterprise web platform, a superadmin panel for complete content control, and a tool to automatically convert PDF question banks into structured exam data. No existing codebase, no technical team on their side.

02. The Solution

We designed and built the entire system with a 3-person team over 6 months. Four separate products, one codebase owner, shipped to production.

Working with QuantumWorks was straightforward. They built our entire platform — the app, the website, and the backend systems — and delivered what they promised. I'd work with them again.
