Klarwin, a European leader in fluid filtration and water treatment, wanted to standardise service-engineer workflows, centralise data for real-time monitoring, and cut on-site interventions. The work spanned three distinct needs: service engineering, station monitoring, and data management.
We built three connected applications. A Service Application for engineers standardises workflows, syncs parts and inventory with the ERP, and speeds invoicing to within days of service. A Monitor Application tracks real-time station data with custom dashboards for different user types and subscription-based client access. A Watcher Application automates data transfer from stations to the server, removing per-station sysadmin work. The backend runs on Laravel and MariaDB, with the monitoring dashboards in AngularJS, handling data from over 100 stations.
In 2026 we took the Service Application through a major refactoring, moving the engineer app to native iOS and Android on React Native and Expo, off the original Ionic build. Engineers service remote water-treatment stations with no signal, so the app now works fully offline and syncs reports, photos, and client signatures back when the connection returns.
From architecture to live systems: architect, build, launch.
