What We Build

What we build with Java

🏢

Spring Boot APIs

Production REST and GraphQL APIs with Spring Boot — battle-tested in enterprise environments and easy to deploy on any cloud.

🔄

Microservices Architecture

Spring Cloud microservices — service discovery, config server, circuit breakers and distributed tracing.

📨

Kafka Event Streaming

Kafka producers and consumers in Java — event-driven architectures for high-throughput, decoupled microservices.

🔗

Enterprise System Integration

Java integrations with SAP, Oracle, IBM MQ and legacy enterprise systems — SOAP, JMS, EDI and custom protocols.

FAQ

Common questions

Java or Go for a new microservice?

Java for enterprise teams already in the Spring ecosystem, or when you need rich library support. Go for teams that want simplicity, faster startup time and smaller containers.

Do you use Java 21 virtual threads?

Yes — virtual threads dramatically simplify concurrent code and improve throughput on I/O-bound workloads. We use them on all new Java 21 projects.

Can you integrate with our existing Java monolith?

Yes — we work with existing Java codebases and can help decompose monoliths into microservices incrementally.

Do you support Kotlin as well as Java?

Yes — Kotlin on the JVM is excellent and we use it for new Spring Boot projects when the team prefers it.
