// PATTERNS

Architecture patterns I work with.

❖Enterprise ERP Architecture
❖Microservices
❖Modular Monolith
❖Event-Driven Architecture
❖CQRS Pattern
❖Repository Pattern
❖API Gateway Ingress
❖Pub/Sub Streaming
❖Worker Pools
❖Circuit Breaker
❖Retry + Backoff
❖Caching Layer
❖Database Replication
❖Horizontal Scaling
❖Idempotence Enforcement
❖Transactional Outbox
// RESILIENCE

Assume something will fail.

Every production component eventually experiences split-brain network states, database lock timeouts, or resource exhaustion.

SERVICE FAILURE

Circuit breaker trips after 5 consecutive 5xx responses. Ingress proxy routes requests to healthy nodes.

DATABASE TIMEOUT

Read queries fall back to cached Redis vectors; write operations buffer in Kafka topics.

CONSUMER SURGE

Queue depth triggers auto-scaling worker containers while dead-letter queues capture unprocessable events.
