The Goal
We are transforming a manual rail inspection workflow into a digital iPad/desktop application. We have a complete React (TypeScript) frontend prototype. We need a Senior Full-Stack Developer to build the secure Backend API, Database, and Offline-Sync Engine.
Core Deliverables
Offline-First Architecture: Implement a sync engine that allows inspectors to work offline in remote areas and sync data when connectivity returns (Conflict resolution required).
Relational Database: Design a strict schema (PostgreSQL) handling Clients - Sites - Assets. Must handle polymorphic assets (Tracks vs. Turnouts have different data fields).
PDF Reporting Engine: Build a server-side generator (Puppeteer) to convert inspection data into "pixel-perfect" PDF compliance forms (WHS-F-06.3).
Inspection Logic: Implement "Anti-Bias" API endpoints that hide historical data until a new value is input.
What We Provide
Existing React Frontend codebase.
Full Engineering Tolerance tables Logic
PDF Templates and Assets
