YazhiSnap: a wedding QR photo engine built for unreliable connectivity
A local-first guest photo workflow that connects QR uploads, host review, watermarking, and a live projector feed without making venue internet the critical path.
Explore YazhiSnapThe challenge
Keep the moment moving when connectivity cannot be trusted.
Wedding guests expect an upload to feel immediate, while photographers need control over what is displayed and retained. Venue connectivity can be inconsistent, so the operating workflow cannot assume a dependable cloud connection.
Operating constraints
Designed around the venue, the host, and the guest.
- Guest phones must join without installing an app.
- The host needs a clear review and approval path.
- Projector output must remain separate from guest upload controls.
- The event should continue operating when internet access is poor.
Architecture
One local event flow, four clear surfaces.
A guest-facing web experience reached through a QR code.
A desktop host application coordinating event state and local services.
Local-network discovery for devices on the venue Wi-Fi.
A dedicated projector view that receives approved photos.
Event workflow
From a guest’s phone to the shared screen.
- 1The host prepares the event and exposes the guest QR code.
- 2A guest joins the venue network, scans, and uploads a photo.
- 3The host reviews the incoming image and applies the event workflow.
- 4Approved photos move into the live display experience.
Outcome
A system that respects both spontaneity and control.
The result is a coherent event system designed around real venue constraints: low-friction guest participation, visible host control, and a live story that can keep moving without relying on cloud latency.
