Web app platform for construction companies

The challenge

Sorba, a Swiss construction technology company, needed to extend their existing desktop solution into a web-based platform without disrupting their current users. The core challenge was building a web app container — essentially an aggregator of functional modules — that lets end-users cherry-pick and deploy diverse applications while sharing the same core database as the desktop application. Both platforms had to operate in sync, accessing identical data without conflicts or duplication.

Our solution

We built a modular web app container using Angular and Node.js with a GraphQL API for efficient cross-module data queries. A visual design builder lets non-technical users tailor and manage application templates — composing custom workflows from a library of functional building blocks via drag-and-drop. The platform connects directly to the existing desktop application's MongoDB database, ensuring both web and desktop users always work with the same data. The modular architecture allows Sorba to add new functional modules independently without affecting existing ones.
