Context
Ventla is an event registration and app platform, trusted by Svedea, People Partner, AMEC and hundreds more organisations since 2011. Organisers build the event, attendees join on the web or in the app, and everything happens live.
That sets a high bar for engineering. An event cannot be moved because of a bug, so the platform has to stay up and responsive while everyone uses it at the same time.
The challenge
Ventla needed one engineering partner that could build the product, ship new features continuously, and keep the platform reliable during live events, without handing work between separate web, mobile and operations teams.
What we did
- 01
The web platform
Built the core platform on .NET and Azure, with Blazor for the organiser experience and Angular and Vue front ends where they fitted best.
- 02
Attendee apps for iOS and Android
Built the mobile apps in Xamarin on the same .NET services, so web and mobile share one set of APIs and one release rhythm.
- 03
Real time during live events
Used SignalR to push live updates to attendees during sessions, and Azure Functions for background work, with secrets kept in Key Vault.
- 04
Built for peak days
Designed the platform on Azure to carry peak days: up to 10,000 participants across 15 events running on the same day.
- 05
Adding AI
Added AI features to the existing platform, on the same services and release process, rather than building a separate product.
Results
- Up to 10,000 participants across 15 events on the same day.
- A product team that grew from two people to more than twenty.
- New features shipped while events ran live.
- One platform across web, iOS and Android, now with AI features.
