# Enterprise Java, engineered for scale

We build robust, maintainable Java systems — from greenfield microservices to the careful, high-stakes work of modernising the legacy estates that keep your business running. Headquartered in London with a world-class engineering team in India, delivering enterprise Java systems for 500+ clients over a decade.

 What we build

## Java solutions we deliver.

Java sits alongside our [Node.js](/technology-services/nodejs/) and [.NET](/technology-services/dotnet/) backend practices as a core, actively maintained service — not a one-off capability we build up for your project.

 ### Expert Team & Proven Experience

10+ years in the industry, with 500+ happy clients worldwide.

  ### Microservices & Spring Boot APIs

Domain-driven microservices built on Spring Boot 3, designed for independent deployability, contract testing, and observability from day one.

  ### Legacy Java Modernisation

Structured migration from Java 8 through to 17 or 21 — module system adoption, records, sealed classes, and the removal of deprecated APIs — without stopping your releases.

  ### Enterprise Integration

Kafka event streaming, IBM MQ, REST and SOAP bridging — we untangle complex integration topologies and bring them under version control and monitoring.

  ### Cloud-Native Java

Containerised JVM workloads on AWS, GCP, and [Azure](/technology-services/cloud-and-devops/) — GraalVM native image for cold-start reduction, right-sizing heap allocation, and Kubernetes-native scaling policies.

Our approach

### A decade of enterprise Java delivery, led from the UK

We’ve built Java systems at every scale: single-service greenfields, distributed platforms handling hundreds of millions of daily events, and careful modernisations of monoliths where the business can’t afford downtime. Building and shipping complex software since 2013, across 500+ enterprise clients, our London team manages everything client-facing, from discovery through delivery sign-off, while our engineering team in India handles the deep technical build: senior oversight without the cost of a fully Western dev team.

Where Java goes right

### Spring Boot, Java 21, and a modernisation path that doesn’t stop your releases

Java is the most deployed enterprise runtime on the planet, and Java 21’s virtual threads alone collapse the performance case for reactive spaghetti code that’s made entire codebases unmaintainable. What’s changed is the delivery model around it: the Java teams that struggle today aren’t struggling because of the language — they’re struggling because the toolchain, the architecture patterns, and the team practices haven’t kept pace. We migrate Java 8 estates through to 17 or 21 using a Strangler Fig approach — module system adoption, records, sealed classes — incrementally, not in one risky rewrite. Clean module boundaries and a solid CI/CD pipeline mean your team ships features without archaeology every sprint, and we build to the LTS roadmap so what we ship today won’t create a migration crisis in three years.

Governance & process

### Four delivery stages, quality gates, and a handover you can rely on

We audit your existing codebase, dependency tree, and deployment pipeline, and define the target architecture and migration risk register before a line of new code is written. Two-week sprints ship a working, tested increment at every close, with unit, integration, and contract tests wired into CI from sprint one — SonarQube quality gates, OWASP dependency checks, and load testing against real traffic profiles before any release. We deploy with zero-downtime blue-green or canary releases, and hand over full runbooks and architecture decision records so your developers take ownership on day one.
