What leaders see
People reconcile the same records repeatedly.
Orders, inventory, production, quality, and shipment status move through exports, re-entry, calls, and side files.

Legacy Modernization · API Development
API Layer Development
Connect legacy manufacturing systems without replacing the core. Legacy ERP, production, warehouse, quality, and custom systems often hold records that portals, analytics, automation, and partner integrations need. We engineer governed APIs around those records while protecting the stable core and documenting ownership, recovery, and change.
01
The Problem
Legacy systems hold critical manufacturing records but cannot exchange them safely.
Integration problems begin when systems exchange fields without agreement about the operating record, timing, ownership, validation, recovery, and exception response.
What is actually happening
The handoff has no governed contract.
Identifiers, source ownership, timing, validation, monitoring, and recovery differ across systems and organizations.
What gets worse
More connections create more uncertainty.
Point-to-point fixes multiply while failures become harder to detect, explain, assign, and recover.
02
What Changes
What API Layer Development includes.
Legacy ERP, production, warehouse, quality, and custom systems often hold records that portals, analytics, automation, and partner integrations need. We engineer governed APIs around those records while protecting the stable core and documenting ownership, recovery, and change.
01
Governed API Contracts
Expose approved legacy records and operations through documented interfaces with explicit identifiers, schemas, validation, versioning, ownership, and support boundaries.
02
Data Abstraction
Abstract legacy data models into modern, clean interfaces. Consumers see logical business objects, not cryptic legacy table structures.
03
Real-Time & Batch
Use request-based, event-driven, or scheduled exchange according to the decision, transaction volume, source-system limits, and recovery requirement.
04
Authentication & Authorization
OAuth 2.0, API keys, and role-based access control. Secure access to legacy data with modern security standards.
05
Rate Limiting & Caching
Protect the legacy system with explicit traffic limits, workload controls, and caching rules tied to acceptable data age and source-system capacity.
06
Monitoring & Logging
API usage dashboards, error tracking, and performance monitoring. Know who's calling what, how often, and whether it's working.
03
How It Fits Your Operations
How API Layer Development fits your operation.
Integration EngineeringWhich records must move, which system owns them, how current they must be, and what happens when exchange fails.
Governance dependencyEach interface needs an accountable source, defined identifiers, validation, recovery, monitoring, and ownership before teams can trust the exchange.
Records and handoffs to connect
orders
inventory and materials
production status
quality records
shipments and exceptions
What must be defined before engineering begins
- What the business needs to change and why.
- Which systems, records, risks, and readiness gaps shape the work.
- What should be built, how it fits the architecture, and in what order.

New material work begins in Launchpad so Metrotechs can validate the operating need, evidence, feasibility, architecture direction, and sequence before engineering begins.
Explore next stepStart With the Operating Problem
Define the smallest sound response and delivery sequence.
Metrotechs determines what the operation actually requires before selecting technology. New material work begins in Launchpad so the evidence, feasibility, architecture direction, priorities, and sequence can be validated before engineering begins.
Metrotechs designs, builds, integrates, and supports the approved solution.
A technical-service request does not bypass discovery. The proposed solution remains a working hypothesis until Metrotechs validates it in Launchpad.

Delivery sequence
How Metrotechs delivers API Layer Development.
Legacy ERP, production, warehouse, quality, and custom systems often hold records that portals, analytics, automation, and partner integrations need. We engineer governed APIs.
01
API Requirements
Define which data and operations need to be exposed. Prioritize by business value -- what integrations are blocked today?
02
Legacy System Analysis
Analyze how to extract data from the legacy system -- direct database, stored procedures, file interfaces, or screen automation.
03
API Design & Build
Design API contracts, build the middleware layer, and implement data mapping between legacy formats and modern JSON/REST.
04
Testing & Security
Load testing to ensure legacy system stability, security testing, and integration testing with consuming applications.
05
Documentation & Onboarding
Publish API documentation, developer guides, and sample code. Onboard internal teams and third-party integrators.

FAQ
Questions that usually decide the scope.
Straight answers to what operators ask before committing budget to this work.
We measure the legacy system's capacity and access paths before selecting an integration pattern. Read replicas, connection pooling, caching, scheduled extraction, and rate limiting are options, but the design must be validated against the actual workload and recovery plan.
