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
What Perl does
Perl is a general-purpose programming language known for text processing, automation and practical system integration. It remains important in web backends, infrastructure tooling, reporting systems and data-heavy applications where dependable scripts must connect files, databases, services and operating-system utilities.
Core ecosystem
Perl professionals work with the Comprehensive Perl Archive Network, commonly called CPAN, which provides reusable modules for web development, testing, database access and data handling. Typical environments include Linux and Unix, Apache, Nginx, PostgreSQL, MySQL, Oracle and containerized deployments. Modern projects may also use PSGI, Plack, Mojolicious or Catalyst.
Typical delivery work
- Maintain and refactor established Perl applications
- Create ETL scripts, reporting tools and data-validation workflows
- Integrate APIs, message queues, databases and legacy systems
- Automate deployments, monitoring and operational tasks
- Add tests, documentation and safer release processes
When specialists help
Companies often seek freelance Perl expertise when a core application has become difficult to change, internal knowledge is limited or a migration needs careful planning. Specialists can assess an existing codebase, remove fragile dependencies and introduce tests without disrupting business operations. In Switzerland, this can support financial, manufacturing, research and public-sector systems while teams collaborate remotely or on site.
Skills beyond Perl
Strong professionals combine Perl with SQL, regular expressions, Linux administration, shell scripting and secure API design. They understand object-oriented and functional styles, package management, version control and automated testing with tools such as prove and Test2. Familiarity with Java, Python, PHP or modern web services is useful when connecting Perl systems to newer components.
Signs of quality
Look for specialists who explain trade-offs clearly and can show how they stabilized real production systems. They should inspect dependencies, define test coverage and document operational risks before changing mature code. For Swiss teams, clear written communication in the agreed working language and reliable coordination across remote or on-site settings matter as much as syntax knowledge.
Frequently asked questions
Quick answers to the questions that come up most around Perl.
Perl is commonly used for text processing, system automation, data transformation, reporting and integration work. It also runs mature web applications and operational tools that connect databases, files, APIs and Unix services.
Perl often offers strong built-in support for text handling and concise automation, especially in established Unix environments. Python or Ruby may be preferred for newer teams or specific application ecosystems, so the right choice depends on existing code, maintenance needs and available skills.
A strong Perl specialist usually works comfortably with Linux, shell scripting, SQL, regular expressions, Git and automated testing. Experience with CPAN, PSGI or Plack, web servers, APIs and deployment pipelines is valuable for production work.
The required depth depends on the system’s age, risk and scope rather than on a simple time measure. Perl work involving undocumented business logic, database migrations or production incidents calls for a specialist who has handled comparable systems and can prove their approach through tests and documentation.
Perl work is often well suited to remote collaboration because code, tests, logs and deployment workflows can be shared securely. On-site sessions in Switzerland may still help with access constraints, stakeholder workshops or knowledge transfer around sensitive legacy systems.
A Perl application may need modernization when releases are risky, dependencies are unsupported, testing is weak or integration requirements have changed. Modernization can mean incremental refactoring, better observability and safer interfaces rather than an immediate rewrite.
Perl remains relevant where automation, data handling and mature operational systems matter. Professionals should be ready to work with legacy code respectfully while applying current practices for security, testing, packaging, documentation and collaboration.
Ask how the specialist would inspect the codebase, protect behavior with tests and manage CPAN dependencies before making changes. Perl quality is shown through readable code, reproducible deployments, clear documentation, secure data handling and improvements that can be monitored in production.
