A subscription-based database of 40,000 construction projects

The main goal was to build a functional, high-performance and intuitive web application that:

• Collects and presents data on thousands of construction projects across Poland.
• Runs on a subscription model, with full functionality available after logging in.
• Keeps data secure to the highest standard.

The biggest challenge was designing an architecture that could manage such a large database quickly and securely, while keeping the system running smoothly and the user interface easy to use.

We planned and delivered the PolandBuild application in four iterations, backed by a solid technology stack and close collaboration with the client:

• Frontend: React.js, providing a dynamic, responsive user interface.
• Backend: Django Rest Framework, powering the API and an admin panel that made managing the database much easier.
• Database: PostgreSQL, for stable and efficient data storage.
• Hosting and infrastructure:

  • Heroku - fast, cost-effective backend deployment and a simpler setup for sending newsletters (a cron-style service).
  • AWS Amplify - frontend hosting with automated CI/CD.
  • AWS Route 53 & S3 - domain and SSL certificate management, plus media file storage.

• A construction project search engine covering more than 40,000 records.
• An admin panel that lets users with the right roles edit content.
• Password reset to help keep user accounts secure.
• Automated newsletter delivery.

• A database of more than 40,000 construction projects from all over Poland, collected and made available in one place.
• A more usable platform that is easier and more comfortable to search.
• Better data and access security thanks to rate limiting and account management features.

PolandBuild shows how steady software development, done in close collaboration with the client, can produce a stable, scalable and genuinely useful tool for a specific industry. Over more than three years, we built and refined a platform that is now a valuable source of information for companies operating in Poland's construction market. Built on proven technologies and a modern cloud architecture, the application gives users quick access to the information that matters most to them.
