Interactive QR Event Platform

I am building a cloud-hosted engagement platform that turns any event screen or live stream into an interactive hub. A unique QR code will appear on the vidiwall and broadcast overlay; guests scan it and land on a mobile-optimised event page that is generated on the fly.

Access must be private, so please wire in Single Sign-On. Once inside, visitors can try their luck in a lottery, vote for the “athlete of the day”, sign up to “be a member”, or dive into the feature that matters most to me—Foto Bomb. Foto Bomb lets users snap a picture on their phone, upload it instantly, and hand control to the admin. From a simple moderation queue I want to pick the best shots and push them straight back to the vidiwall and stream with one tap.

Everything needs to live on AWS for reliability and scale. Think S3 for images, Lambda or Fargate for the back-end logic, CloudFront for snappy delivery, and Cognito (or a similar service) for SSO.

I also need an intuitive admin layer that works both in a web browser and in a lightweight mobile app. From there I should be able to: • switch modules on or off, change copy, colours, and sponsor logos

If you can deliver clean code, clear documentation, and a short hand-off session so my team can maintain it after launch, let’s talk. Budget: EUR 250–750 Skills: PHP, Mobile App Development, iPhone, Cloud Computing, Amazon Web Services, Web Development, API Development
