Java and Spring Boot development: enterprise applications

Java runs a large part of companies' information systems, from banks to manufacturers. With the Spring Boot framework, it builds robust, high-performance applications and APIs maintained over many years. We mainly work where Java is already present: developing new features, APIs to connect your tools, and modernising older Java applications.

Good fit

When to choose Java?

  • A Java information system

    Your company already uses Java: we develop in the same technology.

  • Large volumes

    Heavy processing, many users, performance requirements.

  • A long lifespan

    Long-term support versions and a stable ecosystem.

  • Enterprise integrations

    ERP, databases, internal services, file exchanges.

In all honesty

When it isn't the best choice

For a small business with no existing Java system, a PHP (Laravel) or Node.js application will be faster to develop and cheaper to host and maintain.

Java version upgrade

Moving from an old version (Java 8, for example) to a recent long-term support version.

Modernisation

Gradually splitting a large application into simpler services to maintain.
