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 Java foundation
Jakarta EE is the standard for building secure, modular enterprise applications on Java. Formerly known as Java EE and, earlier, J2EE, it defines APIs and runtime conventions for web services, business logic, persistence, messaging and security. Companies use it when long-term maintainability, clear contracts and reliable operation matter.
Applications and services
Jakarta EE supports systems that connect customers, employees and core business processes. Typical deliverables include:
- REST and web services for internal or public APIs
- Transactional order, finance and workflow systems
- Customer portals and business-facing web applications
- Integration services linking databases, queues and external systems
Specifications and tooling
Its ecosystem includes Jakarta Servlet, RESTful Web Services, CDI, Enterprise Beans, Persistence, Transactions, Messaging and Security. Specialists often work with runtimes such as WildFly, Payara, Open Liberty and GlassFish, alongside Maven or Gradle, JUnit, container images and Kubernetes. They also understand application servers, API gateways, relational databases and observability tools.
When companies need help
Freelance expertise is valuable during a migration from Java EE to Jakarta EE, a platform upgrade or a move from a traditional application server to containers. Companies also bring in specialists to split monoliths into services, improve deployment pipelines, resolve transaction issues or prepare a critical system for cloud operation. In Switzerland, remote collaboration can work well when documentation and communication are precise; on-site work may matter for regulated or complex environments.
What strong specialists deliver
A strong professional maps business requirements to the right Jakarta EE specifications instead of adding unnecessary framework layers. They design clear boundaries, manage transactions deliberately and protect data through well-tested security controls. They can read an existing Java EE codebase, plan namespace changes, modernize incrementally and explain operational trade-offs to technical and business stakeholders.
Choosing the right expertise
Assess experience against the actual runtime, Java version, deployment model and integration landscape. Useful evidence includes migration plans, API designs, automated tests, performance investigations and production runbooks. Look for specialists who can troubleshoot classloading, persistence, messaging and configuration issues, while keeping delivery understandable for distributed teams. A precise scope should state expected integrations, compliance constraints, release process and ownership after handover.
Frequently asked questions
Everything clients usually want to know about Jakarta EE, in one place.
Jakarta EE is used to build secure, transactional enterprise applications and services on Java. It is common in customer portals, internal business systems, APIs, workflow platforms and integrations that need consistent standards across teams and runtimes.
Jakarta EE provides a standardized set of enterprise specifications implemented by application runtimes, while Spring Boot offers an opinionated framework and extensive Spring ecosystem. The better choice depends on existing skills, runtime strategy, governance, migration goals and the level of vendor-neutral standardization required.
A strong Jakarta EE specialist usually understands Java, relational databases, REST, messaging, automated testing and application-server operations. Experience with Maven or Gradle, containers, Kubernetes, CI/CD, observability and cloud infrastructure is also useful when the system runs beyond a traditional data center.
The right level for Jakarta EE depends on the system’s age, integrations, runtime and business risk rather than a fixed number of years. A small API may need focused specification knowledge, while a migration or high-impact transaction system calls for proven architecture, troubleshooting and release experience.
Jakarta EE projects can be delivered remotely when the codebase, environments and decisions are well documented. For Swiss companies, agree early on communication language, working hours, access controls and any on-site needs related to regulated data or operational handover.
Jakarta EE can be a strong fit when standardized APIs, transactions and application-server capabilities support a coherent enterprise system. Microservices frameworks may suit teams that need smaller independently deployed services, but they also introduce more operational and integration overhead.
Before joining a Jakarta EE project, clarify the runtime, Java version, namespace level, deployment model and migration history. Also inspect persistence, messaging, authentication, test coverage, release ownership and the boundaries between the application and surrounding infrastructure.
Quality in Jakarta EE work shows in clear designs, reliable tests, controlled transactions and practical handling of application-server configuration. Ask candidates to explain a migration, diagnose a production issue or review an API design, and look for reasoning that connects technical choices to business risk.
