The app behind America’s leading cat-sitting marketplace

An existing mobile product taken over, then a v2 rebuilt from scratch inside an international team — shoulder to shoulder with the backend developers, and mentoring a junior Flutter developer along the way. A two-sided marketplace: owners looking for a sitter on one side, sitters running their business on the other.

Acquired in January 2026 by Rover, the world leader in pet care.

• Owner side: geolocated search, booking funnel, live chat
• Sitter side: service areas, availability, earnings tracking
• Passwordless authentication with OTP codes and OAuth
• Google Maps and FCM push notifications
