Flowstee needed more than a website — it needed a real operational system tying together three different working contexts at once: office coordinators planning orders, shop-floor workers confirming production stages on tablets, and field crews carrying out installations and service from their phones.
The challenge was making sure all three sides saw the same, up-to-date state of an order with no delays or data conflicts — while each of them needed a completely different interface: a full dashboard in the office, a simplified PIN kiosk on the shop floor, and a lightweight mobile app in the field.
We built the backend as a single source of truth in Django REST Framework, with PostgreSQL as the database for orders, scheduling, service tickets, and a full change history. The office frontend was built in React 19. Instead of server polling, status changes propagate instantly to everyone logged into a given order via WebSocket.
The production kiosk is a separate, simplified view with PIN/QR sign-in instead of an email account — designed for touch use on a tablet. The scheduling and route planner uses the OSRM engine to calculate optimal routes for field crews and detect workload conflicts. Field crews have their own Android mobile app with GPS and photo-based task confirmation.
The platform is live in production and used daily to coordinate orders between the office, the production floor, and field crews — replacing scattered spreadsheets and phone-call arrangements with one shared source of truth about the state of every order.
