“Build us an app like Zillow, but for estate sales.”
The client came with a clear vision: estate sale shoppers needed a better way to discover sales, plan efficient routes across multiple stops, and get early access to the best items before the crowds arrived.
Sellers needed a way to list sales, upload photos and video, manage hours, and track how many people were interested. And the whole thing needed to run natively on iOS and Android — not as a slow web wrapper.
One team. One codebase. Both stores. No exceptions.

TSP route planner
Seller dashboard
Ten features. One launch. Zero compromises.
Real-time sale map
Interactive map with category, price, distance, and date filters. Pins cluster at lower zoom levels and expand into rich cards.
TSP route optimizer
Multi-stop route planner using traveling salesman optimization with departure-time recommendations for max sale coverage.
Offline mode
Saved sales and planned routes persist offline — critical for spotty cell coverage at estate sale locations.
Premier Access ticketing
Early-entry ticketing with QR-code check-in. Stripe handles payments; Cloud Functions issue and validate tickets.
Seller dashboard
Sellers list sales, upload photos and video, set hours, manage inventory, and track analytics — all in-app.
Analytics layer
GA4 + Firebase Performance + Crashlytics wired in from day one. Seller-side dashboard shows foot traffic and listing performance.
FCM push notifications
Native push via Firebase Cloud Messaging for new sales nearby, Premier Access reminders, and seller listing approvals.
iOS + Android native
Single React + Capacitor codebase ships both stores. Fastlane handles screenshot generation, metadata sync, and submission.
Smart routing UX
Optimized departure-time suggestions, turn-by-turn handoff to Maps, and mid-route re-optimization if plans change.
Zero platform lock-in
Client retains 100% of the codebase. No proprietary runtime, no hidden SaaS dependency. Pure open-source stack.
