Latest Project

Featured

A lost pet's fastest way home.

PawBack is a small physical tag with a printed QR code and embedded NFC chip. When someone finds a lost pet, they tap their phone against the tag or scan the QR with any camera — and instantly see the pet's profile with a contact form to reach the owner. No app, no account needed on the finder's side.

The owner gets notified via push, email, and SMS. Built in Düsseldorf together with my wife Fazy.
