The Challenge
Legacy Paper Workflows
Traditional industrial maintenance relied on paper-based work orders, leading to delayed visibility for superintendents and zero real-time tracking of critical repair status.
Integration Friction
Using different languages for Frontend and Backend often leads to “integration hell” and mismatched data structures during the critical hand-off between teams.
Inventory Leakage
Lack of an integrated spare part procurement system meant parts were used without being logged, causing frequent stockouts and operational downtime.
The Solution
Unified “End-to-End” Stack
Leveraged a 100% Node.js stack using NestJS and Next.js to achieve seamless type safety from the database entities down to the UI components.
Robust State Machine
Designed a real-time workflow engine with transition guards that enforces strict industrial maintenance protocols (Draft -> Submitted -> In Progress -> Completed).
Docker Orchestration
Implemented a master Docker Compose strategy that manages multi-repo scaling, ensuring a consistent production environment with NGINX reverse-proxying.
Integrated Procurement
Built an approval chain within the work order flow, allowing mechanics to request spare parts directly with supervisor oversight.
Technical Impact
Deployment Velocity
Delivered a production-ready system in weeks instead of months by eliminating context switching between different programming languages.
Type Safety Excellence
Caught 90%+ of integration bugs at compile time by sharing TypeScript interfaces and Zod validation schemas across the entire stack.
Operational Clarity
Replaced fragmented paper systems with a centralized, data-driven dashboard, providing 24/7 observability into industrial asset health.
