Postgram

Prototype for digital postcards tied to a place. Whoever receives the photo and the message has to go there to open them.

The problem I saw

The more a relationship lives on the phone, the less it depends on where you are. We wanted a mechanic where the place carried weight: a message you cannot read unless you stand where it was left.

Idea and scope

One mechanic only: photo, message, and a point on the map. The recipient sees the notice, but the content stays shut until they get there. No feed, no profiles, no social network around it.

What I built

  • The flow for creating a postcard: photo, message, and location.
  • Proximity unlocking, with the distance on screen as you get closer.
  • The onboarding that explains the mechanic in three screens.

Where it stands

Working prototype. It closes the loop of creating, receiving, and opening a postcard, but it never shipped.

What it shows

  • Turning an unusual condition — physically being somewhere — into a flow people follow without anyone explaining it.
  • Product and engineering inside a three-person team, with AuroraJobs' former CTO and Product Owner.
