API Layer for Legacy ERP

Designed an API layer around an outdated ERP to support integrations with dashboards, external portals, and automation workflows.

The challenge

What the client was facing

A manufacturer's ERP was over 15 years old and locked into a stored-procedure-heavy architecture. Replacing it was a multi-year project — but the business needed dashboards, a customer portal, and supplier integrations now.

What we built

The solution

REST/GraphQL API layer in front of the legacy ERP
Read-replica and CDC pipeline to avoid load on the live ERP
Caching, rate-limiting, and observability built in from day one
Backwards-compatibility contract so legacy ERP upgrades don't break consumers

In production

What it looks like

Illustrative screens — actual client UI, branding, and data redacted under NDA.

AI-first delivery angle

Why AI-first mattered here

AI accelerated the reverse-engineering of stored procedures into clean API contracts. Senior engineers owned schema design, transaction boundaries, and the ERP-replacement migration path.
