Continue valuable software
Existing Java systems can be improved in stages so customers keep using the workflows that already work while the risky parts change deliberately.
Java Backend Development
Java backend development for business-critical systems
We build, continue, and modernise Java backends with Spring Boot and Quarkus for products that need durable business rules, integrations, and operational ownership.
Build on an ecosystem your organisation can support
Java remains a strong product choice when continuity, mature integrations, and long-term ownership matter as much as the first release.
Connect complex business processes
Spring Boot and Quarkus provide practical foundations for APIs, permissions, data access, messaging, and integrations across larger products.
Support long-term ownership
Clear modules, tests, migrations, and operating documentation help internal and external teams keep the backend understandable over time.
Java backend work we deliver
We work on new services and existing platforms, with modernization scoped around the value and risk in the current system.
- Build and extend Spring Boot and Quarkus services, APIs, scheduled jobs, and integration layers.
- Continue existing Java systems and modernise selected modules without forcing a complete rewrite.
- Connect data, identity, permissions, external systems, and mobile or web clients.
- Improve tests, database migrations, deployment, monitoring, and recovery for important workflows.
Spring Boot or Quarkus follows the product context
Spring Boot is often the natural continuation for an established Spring system and its surrounding team. Quarkus can be a strong fit for a service whose runtime model, deployment environment, and existing architecture support it. We evaluate the maintained code and operating constraints before choosing or changing frameworks.
Choose the right path for the product
The technology follows the product, the software you already own, and the team that will operate it.

We make the important product and technology decisions explicit before implementation begins.
Can you modernise a Java backend without replacing it?
Yes. We identify the modules, interfaces, and operating risks that limit the product, then improve them in a sequence that keeps useful software in service.
Do you work with both Spring Boot and Quarkus?
Yes. BayWa Trade and ROE Check-it support our Spring Boot experience, and ROE Check-it also supports our Quarkus experience.
Can Java services support mobile and web products?
Yes. We design the APIs, permissions, data flows, and synchronization around the product workflow, including mobile, browser, and backoffice clients.
