Food safety and traceability app
Hypothetical. Not a client, not a result.
// The problem
A food processor keeps its HACCP logs, sanitation checks and lot records on paper, so an audit means hunting through binders and a mock recall takes far too long.
// What we would build
An Android tablet app on the floor for critical control point checks, sanitation and corrective actions, with lot codes scanned at receiving and production, and a web back office that traces any lot one step back and one step forward on demand.
// What is in it
- Critical control point checks on tablets, with limits and corrective actions prompted
- Cooler and freezer temperatures read from wireless sensors, with alerts out of range
- Lot codes scanned at receiving, production and shipping
- One step back and one step forward trace for any lot, exported for the inspector
- Sanitation schedules and sign-offs with photos
- Record retention set to the rules your food safety team names, such as the Safe Food for Canadians Regulations
// Stack
- Next.js
- React Native (Android tablets)
- PostgreSQL
- LoRaWAN temperature sensors
