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
Solaris at a glance
Oracle Solaris is an enterprise operating system for reliable, secure workloads on SPARC and x86 systems. It is used for databases, transaction processing, telecommunications and other services that depend on controlled change and predictable uptime. Solaris is also known through its former Sun Microsystems roots and the name SunOS.
Core capabilities
Solaris specialists work across operating system administration, performance and lifecycle management. Their work can include zones and Solaris Containers, ZFS storage, DTrace observability, SMF service management, RBAC, patching and system hardening. They may also support legacy applications while planning a controlled transition.
Ecosystem and tooling
The surrounding stack often includes SPARC hardware, Oracle Database, virtualization, network services and enterprise backup. Strong knowledge of ZFS, Live Upgrade or Boot Environments, IPS package management, clustering and shell scripting helps professionals diagnose issues without disrupting critical workloads. Familiarity with Linux and UNIX conventions is useful when systems share operational practices.
When companies need specialists
Companies usually bring in freelance Solaris expertise for focused, high-risk work rather than routine support alone.
- Migrate or consolidate Solaris hosts and zones
- Upgrade operating systems, firmware and packages
- Tune ZFS, storage, memory and service performance
- Investigate outages with DTrace and system logs
- Prepare operational handover and documentation
Project fit in Zurich
Zurich organisations in banking, insurance, research and telecommunications may still run Solaris where stability, established integrations or specialised hardware matter. A freelance specialist can assess an existing estate, coordinate with internal infrastructure teams and document changes for long-term operation. Remote delivery often works well, while sensitive environments may require scheduled on-site access and clear German or English communication.
What strong professionals bring
The best Solaris professionals combine deep UNIX fundamentals with careful change control. They understand boot environments, zones, storage layouts, networking, identity and recovery procedures, and they can explain risks to non-specialists. Look for evidence of incident work, migration planning, automation and tested rollback procedures, not only familiarity with commands.
Frequently asked questions
What clients ask us most about Solaris — answered in short.
Solaris is used for enterprise workloads that require stable operations, mature observability and controlled administration. Common examples include Oracle Database environments, telecommunications systems, transaction processing and applications running on SPARC or specialised x86 infrastructure.
Solaris provides capabilities such as ZFS, DTrace, zones and service management that are deeply integrated into the operating system. Linux usually offers a broader hardware and software ecosystem, so the right choice depends on application support, existing infrastructure, operational skills and migration risk.
A strong Solaris freelancer often brings SPARC hardware knowledge, ZFS storage, shell scripting, networking, identity management and Oracle Database experience. Skills with clustering, backup, virtualization, monitoring and Linux or other UNIX systems are also valuable.
The required depth depends on the system’s criticality and the change being planned. A Solaris specialist handling a production migration, storage redesign or outage investigation should be able to show comparable work, tested rollback plans and clear incident documentation.
Many Solaris tasks can be completed remotely through approved administration channels, including assessment, tuning, patch planning and documentation. Hardware changes, restricted networks or regulated environments may require on-site access in Zurich, with communication agreed in German or English.
Before modifying Solaris, a specialist should confirm the hardware model, operating system release, zones, storage pools, boot environments, dependencies and recovery path. They should also review monitoring, maintenance windows, access controls and the rollback procedure with the responsible team.
Ask for specific examples involving ZFS, zones, DTrace, patching, service management or production recovery. A capable Solaris professional explains diagnosis step by step, records assumptions and can show how changes were tested and reversed safely.
SunOS is the operating system name associated with Sun Microsystems, while Solaris became the product name used for later releases and the broader enterprise distribution. People may still use SunOS when discussing older systems, so a freelancer should clarify the exact release, hardware and tooling involved.
