Backends Built to Outlast the Team That Wrote Them
Java is where enterprises put systems that must not fall over. RASPSYS builds Spring Boot services with the tests, logging and documentation that make them maintainable years later.
What We Deliver
What We Deliver With Java Development
The value of Java is longevity. That only pays off if the code is documented and tested well enough to change safely.
Enterprise Backends
Transactional systems where correctness matters more than speed.
- JPA/Hibernate data layer
- Transaction and concurrency design
- Batch and scheduled processing
System Integration
Connect Java services to CRM, ERP and messaging infrastructure.
- Salesforce and SAP connectivity
- Kafka and JMS messaging
- Legacy protocol bridging
Legacy Modernisation
Move monoliths forward without a risky big-bang rewrite.
- Strangler-pattern migration
- Java version upgrades
- Monolith to service decomposition
Testing & Quality
Coverage that makes refactoring safe rather than frightening.
- JUnit and integration test suites
- Static analysis in CI
- Load and resilience testing
Deployment
Containerised, observable and reproducible.
- Docker and CI/CD pipelines
- Metrics, tracing and logging
- Health checks and alerting
How We Work
Our Java Development Delivery Approach
A structured engagement model that de-risks delivery and gets working output into your team's hands early.
-
Scope
We agree the requirement, the users and what a first shippable slice looks like.
-
Design
Architecture, data model and interface contracts settled before building.
-
Build
Iterative development with automated tests written alongside.
-
Verify
Performance, security and cross-browser or cross-device testing.
-
Hand Over
Documentation, deployment config and team enablement.
Not Sure Java Is the Right Choice?
Most engagements start with a short discovery call. RASPSYS LLP will tell you honestly if another stack suits the workload better.

FAQs
Frequently Asked Questions
The questions we are asked most often about Java Development.
Usually not in one go. Full rewrites overrun and frequently get cancelled with nothing delivered. The strangler pattern - routing functionality to new services piece by piece while the old system keeps running - delivers value sooner and lets you stop at any point.
Spring Boot for the overwhelming majority of business applications: the ecosystem, hiring pool and documentation are unmatched. Quarkus or Micronaut are worth considering for serverless or memory-constrained workloads where startup time matters.
Yes, and it is usually overdue. Moving from Java 8 to a current LTS brings real performance gains and removes a growing security exposure. The work is mostly dependency upgrades and deprecated API replacement; we do it incrementally with the test suite as the safety net.
Regularly. Java services often sit as middleware between Salesforce and enterprise systems that Salesforce cannot reach directly. We build those with governor limits, Bulk API patterns and retry logic designed in rather than discovered.
