About the technology
Enterprise Java
Jakarta EE is the enterprise Java platform used for secure back-end systems, transactional services, and large web applications. It powers APIs, business rules, integration layers, and systems that need clear structure and long-term maintainability.
What it covers
- REST and SOAP services
- CDI, JPA, and Bean Validation
- Security, transactions, and messaging
- Application servers such as WildFly, Payara, and Open Liberty
Where it fits
Teams choose Jakarta EE for business software that must fit into existing Java landscapes. It is common in banking, insurance, public sector work, and internal enterprise systems, including projects in Zurich where stable integration and clean governance matter.
When to bring in help
Freelance specialists are useful when a team needs to modernize Java EE code, move to Jakarta EE namespaces, or fix complex deployment and runtime issues. They also help with performance tuning, security hardening, and refactoring older modules without stopping delivery.
What strong specialists do
Good professionals understand the full stack around the platform: persistence, dependency injection, security, build tooling, and the app server lifecycle. They write code that is easy to test, keep configuration clear, and know how to diagnose problems across the service and infrastructure boundary.
Delivery signals
A strong Jakarta EE engagement usually includes clear service boundaries, predictable releases, and documented integration points. In Zurich, companies often want experts who can work remotely with local teams, review existing code quickly, and communicate well in English and often German when needed.
Frequently asked questions
What clients ask us most about Jakarta EE — answered in short.
Jakarta EE is used for enterprise back-end systems, APIs, and business applications that need transactions, security, and integration with existing Java systems. It fits well when the codebase must be stable, testable, and easy to operate over time.
Jakarta EE is the modern continuation of Java EE after the move to the Eclipse Foundation. The main practical difference is the namespace change from javax.* to jakarta.*, which matters a lot in migration work and dependency compatibility.
A company usually brings in a Jakarta EE specialist for migrations, legacy cleanup, production incidents, or a new enterprise service that must fit an existing Java stack. It is also a good choice when internal teams know Java but need deeper platform knowledge.
Jakarta EE is a standards-based platform with strong support for transaction handling, security, and application-server deployment. Spring is often chosen for its ecosystem and developer convenience, while Jakarta EE is attractive when teams want a more formal enterprise model and vendor-neutral APIs.
A strong Jakarta EE professional usually knows JPA, CDI, REST, security, Maven or Gradle, and at least one application server such as WildFly, Payara, or Open Liberty. Experience with testing, observability, and database design is also important.
Jakarta EE projects vary widely, but the hard parts are usually migration, integration, and production support rather than basic CRUD code. For larger systems, look for someone who has shipped enterprise services and handled deployment, troubleshooting, and refactoring in real environments.
Yes, Jakarta EE work is often well suited to remote collaboration because most tasks are code, configuration, and service integration. For Zurich teams, it helps if the expert can join local meetings when needed and communicate clearly in English, with German as a plus.
A good Jakarta EE specialist explains trade-offs clearly, asks about runtime and deployment early, and can point to real migration or production-support work. Look for clean code, sensible module boundaries, and a practical approach to testing and operational issues.
