Application ownership and further development of test user management (TUM)
Areas of responsibility: Application ownership (Application Ownership / ITSO), application management, incident management, deployment / release management, requirements management, prioritization, further development, automation, and interface management
Technologies: SQL Server, Python, GitLab, UC4, Lieberman, Linux
Responsible for the operation and continuous development of a central application for managing more than 5.000 technical test users and their data.
Gathered and assessed business requirements, independently prioritized further development, and planned and coordinated implementation using agile methods and PI Planning, in close collaboration with the relevant business units and IT teams.
Expanded the central SQL Server database with additional information about test and real users, and integrated further applications through defined interfaces. The modular application used Python-based processing components, with execution and workflows controlled through UC4. This enabled data from different source systems to be automatically transferred, processed, and made available, as well as new test users to be created automatically.
Ensured reliable application operations and continuously optimized and automated existing processes.
Application ownership, modernization, and migration of incident management (TRANT)
Areas of responsibility: Application ownership (Application Ownership / ITSO), application management, incident management, deployment / release management, requirements management, software modernization, migration, interface integration, and quality assurance
Technologies: UC4, Jira, SQL Server, Oracle, Java, Python, Lieberman, Linux, Jai
Responsible for the operation and development of an application that automatically records, processes, and forwards technical incidents in various test environments.
Automated the creation of Jira incident tickets when UC4 workflows were blocked, including routing them to the relevant application managers.
Modernized the application by migrating from Java to Python, moving the database from Microsoft SQL Server to Oracle, and replacing the Jenkins scheduler with UC4.
Integrated the Jira API and used the bank's internal AI solution Jai to support code migration and subsequent validation. Independently and critically reviewed AI-generated results for business and technical accuracy.
Shift lead for operations control in test environments
Areas of responsibility: Monitoring various test systems
Technologies: UC4, TSO, HOST, Azure-Cloud
Responsible for monitoring and controlling automated processing workflows in various test environments, including systems running in the Azure-Cloud.
Monitored UC4 and HOST workflows and analyzed and handled incidents. When processing workflows were blocked, Jira tickets were automatically created through TRANT and assigned to the relevant application owners. In coordination with them, affected jobs were restarted or stopped as needed. HOST processes were also monitored and controlled through OPC.
A multi-shift operation was introduced to ensure stable and as continuous as possible testing.
Test data anonymization manager
Areas of responsibility: Planning/anonymizing/publishing production data for test systems
Technologies: UC4, Informatica (PowerCenter and IDMC)
To ensure test environments could run with real data, production databases were cloned regularly. Production data had to be untraceable in test environments. For this reason, the cloned databases were first anonymized with Informatica PowerCenter and later with Informatica IDMC. Critical tables and columns in the various databases (Oracle, SQL-Server, MongoDB) had to be identified and analyzed at the data level. Rules for handling critical data were agreed with the application owners.

About the technology
Enterprise foundation
Jakarta EE is a standards-based platform for building secure, modular enterprise applications on the Java Virtual Machine. It covers APIs for web requests, dependency injection, persistence, transactions, messaging and authentication. Teams use it for business systems that need clear contracts, long-term maintainability and dependable integration.
Applications and services
Jakarta EE supports customer portals, internal platforms, partner APIs and transaction-heavy back-office systems. Its specifications help teams separate business rules from infrastructure concerns and keep large codebases consistent.
- Design RESTful services with Jakarta REST
- Build server-rendered web applications with Jakarta Faces
- Persist domain models through Jakarta Persistence
- Connect asynchronous workflows with Jakarta Messaging
Ecosystem and tooling
Professionals work with runtimes such as WildFly, Payara, Open Liberty and Eclipse GlassFish. Common project tools include Maven or Gradle, CDI, JPA, Bean Validation and MicroProfile. They also connect Jakarta EE services to relational databases, messaging brokers, identity providers and container environments.
When specialists help
Companies bring in freelance expertise when modernising Java EE applications, moving workloads between application servers or splitting monoliths into services. Zurich organisations may also need specialists who can collaborate remotely or on-site across multilingual product, security and operations teams.
- Upgrade packages from Java EE to Jakarta EE
- Establish deployment patterns for containers and Kubernetes
- Improve API security, observability and test coverage
- Resolve application-server configuration and production issues
What strong professionals know
Strong specialists understand both the specifications and the runtime behaviour behind them. They can trace a slow transaction through persistence, connection pools and messaging, then explain a practical remedy. They also document decisions, protect compatibility and test failure paths instead of focusing only on successful requests.
Choosing the right fit
Look for evidence of delivered Jakarta EE systems with comparable security, integration and deployment needs. Ask how the professional handled version changes, database migrations, transactions and operational support. For remote work, clarify overlap with Zurich business hours, communication language and access to environments before the engagement begins.
Frequently asked questions
What clients ask us most about Jakarta EE — answered in short.
Jakarta EE is used to build secure, modular enterprise applications and services on the Java Virtual Machine. Typical work includes REST APIs, web portals, transactional business systems, messaging workflows and integrations with databases or identity providers.
Jakarta EE is a set of open specifications implemented by application runtimes, while Spring Boot provides an opinionated application framework and extensive Spring modules. The right choice depends on existing standards, runtime strategy, team familiarity, deployment needs and the level of control required over application infrastructure.
A strong Jakarta EE specialist usually brings Java, SQL, REST, testing and application-server knowledge. Experience with Maven or Gradle, Docker, Kubernetes, MicroProfile, messaging systems, OAuth or OpenID Connect can also be important for production work.
The need depends on the system’s risk and scope, not on a fixed number of years. A professional modernising a Java EE application should understand namespace changes, compatibility and migration testing, while a new service may require stronger skills in security, observability and cloud deployment.
Jakarta EE work is often suitable for remote collaboration because source code, build pipelines, documentation and environments can be shared securely. Zurich teams should agree on working-hour overlap, language expectations, access controls and a clear process for architecture and production decisions.
Choose Jakarta EE when standardised APIs, managed transactions, application-server capabilities and long-lived enterprise support matter. A lighter framework may be preferable for a small service with limited infrastructure needs, but the comparison should include operations, security and future maintenance.
Ask the Jakarta EE professional to explain a comparable system, including its runtime, persistence model, security design and deployment process. Good answers connect technical choices to business risks and cover testing, failure handling, monitoring and documentation rather than only listing APIs.
Jakarta EE is the successor to Java EE, which was the former name of the enterprise Java platform. The move also introduced the jakarta.* namespace, so migrations require attention to source code, dependencies, application-server versions and compatible libraries.
