Core Service #6
Platform Integration & System Design
APIs, data flows, and third-party systems-done safely.
We design and review integrations so platforms remain secure, observable, and maintainable as they grow
API Design and Authentication
RESTful APIs, GraphQL, gRPC. OAuth, JWT, API keys. Design APIs that are secure and scalable.
Third-Party Integrations
Payment processors, SaaS platforms, identity providers. Connect safely.
Event-Driven vs Synchronous
When to use events, when to use API calls. Message queues, webhooks, and streaming.
Data Ownership & Trust Boundaries
Who owns what data? Where are the trust boundaries? How does data flow between systems?
Failure Handling & Observability
Circuit breakers, retries, timeouts. Logging, metrics, and distributed tracing.
What We Cover
API Design
RESTful, GraphQL, gRPC. Versioning, pagination, rate limiting.
Authentication
OAuth, JWT, API keys, mutual TLS. Choose the right auth for each integration.
Third-Party Integrations
SaaS platforms, payment processors, identity providers. Secure connection patterns.
Event-Driven Patterns
Message queues, event streams, webhooks. When to use async vs sync.
Data Ownership
Trust boundaries, data flows, and who owns what data.
Observability
Logging, metrics, distributed tracing, and alerting.
Deliverables
Visual diagrams showing how systems connect, data flows, and trust boundaries.
How to secure and monitor each integration. Authentication, error handling, retries.
What happens when integrations fail? How to handle load spikes? Circuit breakers and fallbacks.
Integration Patterns We Design
Built to Integrate
Modern platforms are composed of many systems. We design integrations that are secure, reliable, and maintainable.REST API Design
Resource-oriented APIs, proper HTTP methods, pagination, filtering, versioning.
Event-Driven Architecture
Event sourcing, CQRS, message queues (SQS, Kafka, RabbitMQ), pub/sub patterns.
Webhook Security
Signature verification, replay protection, and secure payload handling.
Distributed Tracing
OpenTelemetry, trace context propagation, request tracking across services.
Design My Integrations
Let's design API architecture, integration patterns, and observability for your distributed systems.
