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.
