SYSTEM INTEGRATION & API ENGINEERING

Eliminate data silos with high-availability API middleware.

Map legacy endpoints, standardize data schemas, and secure permissions. We engineer high-concurrency, real-time integration middleware with full observability.

VERIFIED OUTCOMES

Measurable System Integration Outcomes

We operated 5 siloed POS and inventory setups. LSG TECH built a unified API layer that synced stock globally in real time, cutting response times by 60%.

Marcus Lin CTO · Retail Omnichannel Corp

Handling millions of high-throughput API calls during flash sales, the event-driven middleware maintained 99.99% uptime with zero packet loss.

DECISION SUPPORT

Key considerations before initiating system integrations.

Can you integrate legacy systems without official API support?

Yes. We build database adapters, CDC pipelines, or custom wrapper layers to expose legacy data securely without touching old codebases.

How do you maintain data security across distributed services?

We deploy unified API Gateways with OAuth 2.0/JWT, mTLS encryption, rate limiting, data masking, and distributed audit logging.
