So I built restaurants their own branded camera —
one NFC tap or QR scan opens the camera, adds
the business to the photo, and makes it ready to share.
So I gave restaurants their own branded camera — a simple QR or NFC tap that opens a beautiful browser camera to capture and share photos.
Expanded the touch targets for resizing and rotating stickers on mobile.
So I built MenuTap — a simple NFC tap that brings your menu, Wi-Fi, reviews, games and more to one tap.

FoodSpot Mobile introduced a new post-purchase surface: the UGC Receipt — a digital receipt that invites customers to photograph their order and create branded, organic content immediately after delivery.

Start with a real frustration. What would a better experience look like?
I don’t guess where it broke.
I reproduce, inspect, trace,
find the cause and fix it.
Dragging and deleting worked, but resizing and rotating stickers felt too precise on mobile. I compared the interaction directly with Instagram’s sticker controls and realized our interactive touch area was smaller. The touch target was expanded without unnecessarily making the visible control larger, making the interaction easier to use on a phone.
When authentication appeared to complete but the app stalled or returned an error, I started with the callback URL and browser console. If the frontend didn’t explain enough, I traced the problem through Supabase Edge Function logs and database access. In some cases, RLS/data access was blocking the expected operation.
Some keyboard shortcuts weren’t being recognized consistently, and microphone permission could be requested again after relaunching the app. I tested different hotkeys and repeated launch/permission scenarios on macOS until the shortcut handling and permission flow behaved reliably.
