What our java development services cover
Enterprise-grade JVM engineering, from greenfield services to estates older than some of our engineers.
Enterprise backends and services
High-throughput JVM services with typed domain models, transactional integrity, and the operational discipline (metrics, tracing, graceful shutdown) that enterprise scale demands.
- ✓Modern Java LTS (17/21)
- ✓Spring or Quarkus per fit
- ✓JPA with sane transaction boundaries
- ✓Resilience patterns (circuit breakers, retries)
High-throughput data processing
Batch and streaming pipelines on the JVM: Kafka consumers, scheduled processing, and reconciliation jobs that are idempotent because duplicates are a when, not an if.
- ✓Kafka and event-driven pipelines
- ✓Spring Batch processing
- ✓Idempotent, replayable jobs
- ✓Backpressure and dead-letter handling
Legacy java modernisation
Java 8 monoliths, EJB-era estates, and abandoned build scripts brought forward incrementally, with tests around behaviour before anything structural moves.
- ✓Java version upgrade paths
- ✓Application server to containerised runtimes
- ✓Test harness around legacy behaviour
- ✓Strangler-pattern decomposition
API platforms and integration
SOAP legacies, REST surfaces, and the bridging between them, with contract tests keeping partner integrations honest across releases.
- ✓REST with OpenAPI documentation
- ✓SOAP interoperability
- ✓Contract and consumer testing
- ✓Versioned, deprecation-aware APIs
JVM performance engineering
Profiling-led performance work: GC behaviour, allocation hotspots, and connection pooling tuned against load tests rather than folklore.
- ✓GC tuning and analysis
- ✓Heap and allocation profiling
- ✓Database and pool optimisation
- ✓Load tests to numeric targets
Migration off the monolith
Where a monolith genuinely blocks delivery, we decompose along data boundaries with API development discipline, and say plainly when a modular monolith serves you better.
- ✓Domain-driven boundary analysis
- ✓Incremental service extraction
- ✓Shared-nothing data ownership
- ✓Rollback-safe cutovers
What every engagement includes
Every Java project ships with the following, agreed in writing before the first sprint begins.
Discovery workshop
A structured workshop maps your goals, users, and constraints into a scoped Java roadmap with a fixed written quote before any sprint starts.
Named senior team
You get named, senior engineers with CVs you can review, not a rotating bench. The people in the kickoff are the people who ship.
Sprint demos every two weeks
Working builds are demoed live each cycle with CI running on every merge, so progress is visible in software, not slideware.
100% source-code ownership
All Java source, configurations, designs, and documentation transfer to you on delivery with no licensing strings or vendor lock-in.
60 days of post-launch support
Engineering time is on standby for two months after go-live to triage defects, tune performance, and stabilise the release at no extra cost.
12 months of free updates
Compatibility updates, security patches, and framework upgrades ship free for a full year after handover.

Where java is the right call
Java earns its keep on long-lived, high-consequence systems: banking, telecoms, logistics, and government platforms where stability, transactional correctness, and a deep talent pool matter more than iteration speed. The modern JVM is fast, and the ecosystem's maturity is a feature at enterprise scale.
For lighter-weight services on the same JVM, our Spring Boot development services page covers the microservice path in depth, and our Kotlin development team covers the modern JVM language option where team preference points that way.
The stack behind our java builds
What we use by default, and why.
Language and runtime
Current Java LTS with records, sealed types, and virtual threads where they fit, on current JVM runtimes, with upgrade cadence planned rather than postponed.
Frameworks
Spring Boot for most services, Quarkus for fast-startup and native-image cases, plain frameworks where a full stack adds ceremony without value, decided per project.
Data and messaging
PostgreSQL or Oracle with Flyway-managed migrations, Redis for caching, Kafka for event flow, and connection pooling tuned to the workload rather than left at defaults.
Testing and quality
JUnit 5 with Mockito, Testcontainers for database-backed integration tests, ArchUnit rules enforcing architecture, and static analysis (SpotBugs, Error Prone) in CI.
Build and delivery
Gradle or Maven with reproducible builds, Docker images built in CI, Kubernetes or ECS deployment, and OpenTelemetry tracing wired before the first production deploy.
AI integration
LLM orchestration with typed clients and evaluation harnesses, document processing pipelines, and AI-assisted code review across our Java projects under human ownership.
How a java project runs
Six stages with sign-off gates, built for enterprise constraints.
- 01
Discovery
Domains, transaction requirements, integration surfaces, and compliance constraints mapped with your stakeholders, ending in a fixed written quote and an architecture risk register.
✓ step 01 complete - 02
Architecture blueprint
Service boundaries, data ownership, and API contracts designed and reviewed before implementation, with the decision record written so future teams know why.
✓ step 02 complete - 03
Foundation sprint
CI, containerisation, observability, and environments scaffolded first. A walking-skeleton service deploys to staging before feature work starts.
✓ step 03 complete - 04
Sprint delivery
Two-week sprints with live demos. Static analysis, architecture rules, and the test suite gate every merge, and contract tests keep integrations honest.
✓ step 04 complete - 05
Load and hardening
JVM and database profiling against the numeric targets from discovery, failure-mode drills, and security review before launch, with results documented.
✓ step 05 complete - 06
Support and handover
60 days of included support, 12 months of free updates, and runbooks plus architecture decision records written for the engineers who inherit the system.
✓ step 06 complete

Why enterprises choose our java teams
Enterprise systems expose weak engineering slowly and expensively. Ours is built for that exam.
Modern java, not nostalgia
Records, sealed types, and virtual threads are tools we use, not features we read about, so your platform is current rather than a museum of 2014 idioms.
AI-augmented delivery
AI tooling accelerates test generation, refactoring, and review across our Java projects while senior engineers own every design and architecture decision.
Testcontainers-grade rigour
Integration tests run against real databases and brokers in CI, so the suite catches what mocks quietly hide and your deploys are boring in the good way.
Legacy modernisation playbook
We have moved Java 8 estates forward without big-bang rewrites, and we bring tests, strangler patterns, and patience to the job in that order.
Operational maturity
Metrics, tracing, and alerting ship with the first deploy, so production incidents are diagnosed in minutes rather than reconstructed over days.
Track record since 2010
9,000+ projects delivered across 25+ countries, including enterprise JVM systems serving millions of users.
