What you'll own?• Existing production modules — RFID tracking, real-time weight and production data (WebSocket), delivery orders and invoicing — including maintenance, bug-fixing and enhancement. • New features across the full stack: Next.js front end, NestJS back end, PostgreSQL. • Real-time data flows between plant hardware (RFID cabinets, weighing and production systems) and the platform. • Database design, queries and performance in PostgreSQL. • Testing, deployment, documentation and technical direction — so platform knowledge lives in the codebase and runbooks, not in one person's head.
