Programming services for the UK

Go & Java

High-performance microservices for critical UK workloads

High-performance microservices for critical workloads, stable API contracts between services, concurrency tuning for maximum throughput, integration with existing enterprise systems, automated testing on business flows.

Go 1.22 for low-overhead microservices, Java 21 (LTS) with Spring Boot 3 for enterprise integrations where the existing codebase is already on the JVM. Both stacks come with proper observability (OpenTelemetry SDK, Prometheus metrics, structured JSON logging), gRPC or HTTP/2 transport, and protobuf-defined contracts when you need stable cross-team integration.
