Make Disconnected Systems Operate as One

Connect fragmented business platforms through API design, event-driven integration, gateways, authentication, rate limits, and observable integration flows.

Application change with controlled dependencies

Turn disconnected internal systems, SaaS platforms, financial tools, CRM, ERP, and AI services into governed, observable integration architecture.

Synchronous API

Webhook flow

Queue or event stream

Turn disconnected internal systems, SaaS platforms, financial tools, CRM, ERP, and AI services into governed, observable integration architecture.

Build Surface Where implementation risk concentrates

01 REST API design Request/response business operations
02 GraphQL where justified External platform change notifications
03 Webhooks Durable asynchronous work
04 Event-driven integration Shared access and policy boundary
05 Message queues Request/response business operations
06 API gateways External platform change notifications

Engineering Matrix

How design choices become maintainable code

How design choices become maintainable code
Architecture Element	What HRHK Evaluates	Publication Value
Synchronous API	Request/response business operations	Schema, auth, rate limits, error contracts
Webhook flow	External platform change notifications	Verification, retries, replay handling
Queue or event stream	Durable asynchronous work	Idempotency, ordering, dead-letter strategy
Gateway layer	Shared access and policy boundary	Identity, quotas, observability, versioning

Design an Integration Architecture

Start with the application behavior, integration boundary, or deployment constraint. HRHK can map the code, data, platform, and operational dependencies before changing production systems.
