Middleware Development

The connective tissue of modern software architectures. We design and build the middleware layers — message brokers, API gateways, event buses, and service meshes — that make complex distributed systems work reliably.

What Is Middleware?

Middleware sits between applications and infrastructure, handling cross-cutting concerns that individual services shouldn't need to solve independently: authentication, routing, rate limiting, transformation, messaging, and reliability patterns like circuit breakers and retries.

Well-designed middleware dramatically reduces complexity across your system — centralizing policies, improving observability, and enabling services to focus on business logic rather than plumbing.

Middleware Solutions We Build

  • API GatewaysCustom or managed gateways (Kong, AWS API Gateway, custom Node.js/Go) with auth, rate limiting, routing, and observability.
  • Message Brokers & Event StreamingKafka, RabbitMQ, and NATS implementations for reliable async communication between services.
  • Event-Driven ArchitectureEvent sourcing, CQRS patterns, and outbox pattern implementations for eventual consistency.
  • Data Transformation PipelinesStream processing and schema transformation layers for heterogeneous data formats.
  • Authentication & Authorization MiddlewareJWT validation, OAuth 2.0 flows, and RBAC enforcement as centralized middleware components.
  • Resilience PatternsCircuit breakers, bulkheads, retries with exponential backoff, and graceful degradation built into your service layer.

When Do You Need Custom Middleware?

Multiple services with shared auth or rate limiting requirements
Legacy systems that need protocol translation
High-throughput async workflows between microservices
Complex routing logic beyond off-the-shelf gateway capabilities
Multi-tenant SaaS platforms with tenant-aware routing
Regulated environments requiring detailed audit logging
