Last position:
Julius Bär
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
Unix foundations
Unix is a family of operating systems and a design philosophy built around small, composable tools, clear permissions and powerful text-based interfaces. Its principles shaped BSD, Linux, macOS and many enterprise systems. Companies use Unix environments for dependable servers, research platforms, network services and core infrastructure.
Systems and workloads
Unix specialists support systems that must remain stable, observable and secure under sustained demand. Their work can include:
- Operating system installation, upgrades and hardening
- Shell scripting for repeatable administration
- Web, database and application hosting
- Backup, recovery and service monitoring
- High-availability and disaster-recovery setups
Tools and ecosystem
The Unix ecosystem includes Bourne-compatible shells, awk, sed, grep, make, cron, SSH and standard POSIX utilities. Depending on the environment, specialists also work with FreeBSD, OpenBSD, Solaris, AIX, macOS or Linux, along with Git, Ansible, containers, systemd and network tooling. Strong command-line habits remain central even when graphical management layers are present.
When companies need specialists
Freelance Unix expertise is useful during migrations, security reviews, platform upgrades and urgent operational work. It can also close a skills gap when internal teams inherit older systems, need dependable automation or must document infrastructure before a major change. In Zurich, specialists may collaborate remotely or on site with financial, research, manufacturing and technology teams.
Skills that matter
A capable Unix professional understands processes, filesystems, permissions, networking, logging and performance behavior. They write maintainable shell scripts, investigate failures methodically and distinguish an application problem from an operating system or network issue. Experience with change control, documentation and incident response is equally important for production environments.
Choosing the right expert
Look for evidence of work on the Unix variant and workload your system actually uses. Ask how the specialist approaches access control, patching, rollback plans, monitoring and knowledge transfer. For Zurich-based collaboration, clarify on-site expectations and working-language needs early. The strongest professionals explain trade-offs plainly and leave behind automation and documentation that others can maintain.
Frequently asked questions
Not sure where to start with Unix? These answers cover the essentials.
Unix is used for servers, network services, scientific computing, enterprise applications and infrastructure that requires strong stability and control. Its command-line tools and permission model also support automation, security operations and repeatable system administration.
Unix refers to a family and design tradition that includes systems such as BSD, Solaris and AIX, while Linux is a Unix-like kernel and operating system ecosystem. Windows Server uses different core tools and administration patterns, so the best choice depends on application compatibility, existing skills, vendor support and operational requirements.
A strong Unix specialist often brings shell scripting, TCP/IP networking, SSH, Git, databases, web servers and automation tools such as Ansible. Knowledge of cloud infrastructure, containers, monitoring and security is valuable when Unix systems form part of a wider platform.
The right Unix professional depends on the risk and scope of the work. Routine scripting may need focused operational expertise, while migrations, kernel-level troubleshooting, security hardening or high-availability design call for someone who has handled comparable production environments.
Unix work is often well suited to remote collaboration because systems can be accessed securely and changes can be reviewed through version control and ticketing tools. Zurich companies should still define access procedures, on-site needs, meeting habits and preferred working language before the engagement begins.
On-site Unix support can help when specialists must connect to restricted infrastructure, inspect physical systems or work closely with operations teams. Remote delivery is usually practical for scripting, monitoring, documentation and many migration tasks, provided secure access is available.
Ask for concrete examples involving the same Unix variant, workload and operational constraints as your project. A good specialist explains diagnostic steps, protects production systems with testing and rollback plans, and documents commands, decisions and recovery procedures clearly.
A Unix freelancer may deliver hardened system configurations, shell scripts, automation playbooks, monitoring rules, migration plans and recovery documentation. Agree on acceptance criteria, access boundaries and handover materials so the result remains useful after the engagement ends.
