A digital construction marketplace portal designed to connect project opportunities with estimation services, helping contractors and construction professionals manage projects through a more organized online platform

Context, constraints, and the business problem we set out to solve.
QTO House is a SaaS-based construction marketplace and estimation platform created to simplify how contractors, estimators, and construction businesses discover and manage project opportunities. The platform brings construction projects and estimation-related activities together within a centralized digital environment.
At the core of QTO House is a project marketplace where users can browse available construction projects, purchase relevant opportunities, and gain immediate access to the associated project documents. This creates a more convenient and structured process for moving from project discovery to the estimation stage.
The platform also provides a dedicated dashboard that helps manage essential business and customer activities, including subscriptions, contacts, discounts, sample requests, account information, and transactional communications. Automated notifications and organized workflows reduce repetitive manual tasks and help maintain a consistent user experience.
From a technology perspective, QTO House combines a Django REST backend with a React-based frontend, providing a responsive interface supported by secure API-driven functionality. Its scalable architecture and reusable components create a strong foundation for managing a growing marketplace while keeping the platform efficient, reliable, and easy to use.
Overall, QTO House demonstrates how a purpose-built construction estimation platform can connect project discovery, purchasing, documentation, customer management, and automated communication within one streamlined digital solution.
