Udo W.
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
Perl in Modern Enterprise Infrastructure
Perl remains an indispensable foundation for mission-critical enterprise systems, batch processing, and network automation. Organizations rely on the language to parse massive text streams, manage complex file transformations, and run robust system administration tasks. Its maturity ensures unmatched stability and backwards compatibility across Unix and Linux environments.
Typical Use Cases and Project Scopes
- Modernizing legacy Perl 5 scripts and monolithic backends
- Building and maintaining CPAN-dependent financial batch pipelines
- Writing network monitoring tools and automation utilities
- Creating custom ETL workflows for high-volume database operations
- Implementing secure data sanitization and log analysis solutions
Core Ecosystem and Tooling Standards
Specialists in this ecosystem leverage comprehensive tools from CPAN to build maintainable applications. Modern frameworks such as Mojolicious, Catalyst, and Dancer power modern web interfaces and REST APIs. Strong practitioners use Moose or Moo for clean object-oriented architecture, DBI for reliable database persistence, and Test::More or Test2 to enforce continuous automated test coverage.
The Local Market Landscape in Zurich
In Zurich, demand for this expertise centers heavily on financial institutions, private banks, insurance carriers, and scientific research facilities. These organizations operate stable, long-running backends that handle transaction settlement, reporting, and secure inter-system communication. While remote delivery is common, Zurich-based operations frequently value local compliance awareness and availability for occasional on-site consultations.
Key Qualities of Senior Specialists
Distinguishing a top practitioner requires evaluating their approach to code hygiene and architectural clarity. Expert talent avoids unreadable one-liners, preferring strict encapsulation, rigorous testing, and comprehensive documentation. They navigate legacy procedural scripts with confidence while refactoring components into maintainable object-oriented code, decoupling archaic modules, and optimizing execution bottlenecks without introducing regression risks.
When to Engage External Freelance Support
- Bridging internal knowledge gaps when core systems lose institutional memory
- Accelerating time-sensitive database migrations and API integrations
- Performing codebase refactoring before major infrastructure upgrades
- Auditing mission-critical scripts for performance and security compliance
Frequently asked questions
Key details about Perl, drawn from the questions we get asked most.
Organizations rely on Perl for complex text processing, data pipeline automation, system orchestration, and backend transaction processing. It frequently powers mission-critical glue code and legacy enterprise portals where stability and raw parsing speed are mandatory.
While Python dominates new web and data science builds, Perl 5 offers exceptional backward compatibility and superior regular expression processing out of the box. Teams continue maintaining it because rewriting stable, high-throughput pipelines into alternative runtimes often introduces significant business risk and high migration costs.
A capable practitioner builds modern Perl applications using frameworks like Mojolicious, Dancer2, or Catalyst. They also write clean object-oriented code utilizing Moose or Moo, and maintain production stability through extensive test suites built on Test::More.
Yes, highly skilled specialists understand Perl codebases deeply enough to decouple business logic from legacy scripts and migrate components to modern tech stacks. They design safe transition paths, write automated regression tests, and ensure continuous data integrity throughout the transition.
Zurich hosts numerous financial service providers, insurance corporations, and research institutions running established core platforms built on Perl. These firms require vetted professionals who understand local regulatory standards, security mandates, and complex back-office systems.
Resolving tangled legacy scripts requires a senior Perl specialist with deep Unix systems knowledge, strong relational database skills, and hands-on experience in defensive programming. Junior professionals often struggle with complex CPAN dependency trees and idiomatic syntax found in older applications.
Most Perl refactoring and development can proceed remotely without operational friction. However, institutions in Zurich occasionally prefer professionals who can join on-site design workshops or navigate secure internal networks within Switzerland's time zone.
Review whether the specialist adheres to Perl::Critic standards, avoids archaic global variables, and implements strict mode across all modules. Strong candidates write modular, self-documenting code with comprehensive automated testing and transparent dependency handling.
