Event-driven backends and microservices

APIs and services in Java, Python, Go or Node.js, designed to be handed over, not held hostage.

We have built these in four languages across a decade, which mostly means we have opinions about when microservices are the wrong answer. Every engagement ends with documentation, tests and a walkthrough, so your team can own the system afterwards.

What you get

REST, GraphQL and gRPC APIs
Event-driven architecture with Kafka and queues
Distributed caching with Redis
Service decomposition and migration off monoliths
OpenAPI documentation and integration tests
