eBay for cows, but it actually works when the WiFi is garbage
PaddockHammer is an offline-first livestock auction platform built for rural sale yards where connectivity is a suggestion, not a guarantee. It handles the entire auction lifecycle — lot intake, health cert verification, bidder registration, and live price discovery — syncing everything the moment a signal appears. Cattle brokers in Queensland are already using this instead of paper clipboards and they are never going back.
- Offline-first bidding engine that survives complete network blackouts without dropping a single lot
- Conflict-free sync resolves up to 847 concurrent bid events per session across disconnected nodes
- Integrates with the NLIS cattle traceability database for real-time RFID tag verification
- Health certification pipeline validates, timestamps, and countersigns vet docs on device. No upload required.
- Bidder registration with identity verification, deposit hold, and limit enforcement baked in from day one

PaddockHammer runs as a set of loosely coupled microservices behind a local-first sync layer powered by CRDTs, so every device in the yard is a full peer with zero dependency on a central server during a sale. Transactional lot and bid data lives in MongoDB because the document model maps cleanly to how auctioneers actually think about livestock, and the entire event stream is replicated to Redis for long-term audit storage and regulatory compliance. The mobile clients are React Native with a SQLite journal that queues mutations until the sync engine can flush them upstream. There is no single point of failure. I designed it that way on purpose.
