System Integration & Architecture Upgrade

Core legacy systems often hold critical business logic; a full rewrite carries high risk. Common practice is outcome-first: inventory applications, data flows, and integration points, then pick two or three high-value interfaces for quick wins. Technically: API facades, Strangler Fig pattern, event-driven design, and middleware orchestration expose modern interfaces without downtime.

Typical capabilities

• REST/GraphQL gateways with authentication (OAuth, API keys) and rate limiting
• Cross-system master data and customer identity alignment; batch and real-time synchronization
• Hybrid cloud, containerization, and observability to support canary releases and troubleshooting

Success criteria

Measure integration latency, error rates, reduction in manual steps, and delivery cycle time—avoid judging progress only by how new the stack looks.
