Hire Expert Java Developers
Senior Java engineers for business systems, APIs and services that have to run for years.
Java at Beaver Development
Java runs a large part of the world's business software, from banking and insurance to logistics. It is fast on the JVM, backward compatible and has long-term support releases, which suits systems that live for many years. Our Java engineers build and maintain these systems for clients, inside your team or as a complete project.
What we build with Java
- REST APIs and services with Spring Boot
- Business applications with JPA and Hibernate
- Message-based integrations with Kafka or RabbitMQ
- Upgrades from older Java and Spring versions to current releases
- Tests with JUnit and Testcontainers, wired into CI

Frequently Asked Questions
Do you offer full Java development teams or individual developers?
Both. You can add one senior Java developer to your team or hire a full cross-functional team with DevOps and QA included.
Which Java frameworks do your developers use?
Mostly Spring Boot, Spring Data and Spring Security, Hibernate, Kafka, and Maven or Gradle builds. We adapt to the stack you already run.
Do you provide ongoing maintenance and support?
Yes. We take over existing Java applications, upgrade them to supported Java and Spring versions, and support them under a maintenance plan.
Can you work with our existing team?
Yes. Our developers work in your repositories, your sprint process and your code reviews, and follow the conventions your team already has.
What engagement models do you offer?
We provide flexible outstaffing, dedicated teams, and fixed-scope project delivery, all under strict NDAs and data protection compliance.
