API Layer Development
Build a governed API layer over legacy manufacturing systems so new applications can use approved records without requiring core replacement first.

Metrotechs delivers Integration Engineering, Manufacturing Portals, Operational Analytics, Workflow and Exception Automation, and Custom Software Engineering. We begin with the manufacturing operating problem, then select the smallest sound service combination and supporting technology.
These are the customer-facing services Metrotechs provides. ERP platforms, cloud infrastructure, data platforms, and AI tools may support the work, but they are selected inside the service—not presented as the reason for the engagement.
