Context
A calibration services provider operating 10 US lab locations, where the ERP is the operational system of record for every work order and certificate.
Constraint
The business ran on a slow legacy .NET application that could not scale across labs, regions, or compliance regimes.
Architecture
A React/Node Calibration ERP replaced the legacy .NET application across all 10 lab locations: real-time work-order tracking, certificate generation, audit trails, and a self-service customer portal on top of a migrated relational data model.
