Adyoutiser

Adyoutiser is a platform for digital out of home advertising — advertising on digital screens in public space. Advertisers use it to book screen time, upload their creatives and decide where and when they run. What normally runs through quotes, email threads and hand-kept booking sheets happens in a single interface instead.

The platform holds three things together at once: the available screens with their locations and time slots, the campaigns with creatives and run times, and the reporting that shows what a running campaign has achieved so far. Booking is the critical part — a screen can only be allocated once for a given period, even when several bookings arrive at the same time.

NDVDL is the development partner behind that platform. The booking and management interface, the backend services, the data layer and the operation on AWS come from us. Adyoutiser is an independent product with its own business; we are responsible for the technology behind it — from the first line of code to running it in production.

Digital advertising space is a limited, time-bound resource: a screen can only be assigned to one campaign for a given period. A booking system therefore has to check, on every new booking, whether the requested time slot overlaps with an existing booking for the same screen — reliably, even when several bookings arrive at the same moment. That is exactly what relational databases with transaction guarantees are built for: they prevent two simultaneous writes from double-booking the same screen.

The second requirement is real-time reporting: campaign results need to be available continuously, not the next day. That calls for a backend architecture that separates booking, campaign, and analytics logic while still working from the same consistent data — and that doesn't slow down as the number of campaigns and screens grows. Concurrency on the backend and an operating environment that can absorb traffic spikes aren't incidental here; they're a baseline requirement for a usable platform.
