A full-stack construction estimation marketplace and client management portal built with React and Django, enabling contractors to browse, purchase, and access construction projects with automated workflows, subscriptions, and secure payment-based file delivery.

Context, constraints, and the business problem we set out to solve.
QTO House is a complete SaaS-based construction estimation platform designed for contractors, estimators, and construction businesses. The portal allows users to explore a marketplace of construction projects, purchase them securely, and instantly receive access to project files after payment. It also includes a powerful dashboard for managing accounts, contacts, subscriptions, discounts, sample requests, transactional emails, and customer activities. Built with a scalable Django REST backend and a modern React frontend, the platform delivers a smooth, responsive, and highly automated experience. It streamlines the entire estimation-to-delivery workflow with reusable components, secure APIs, automated email notifications, and a clean, professional UI.
