Summary

Industry-neutral implementation of software projects with intensive business process analysis. Use of the following tools (Aris and Adonis).
Extensive industry knowledge in insurance: Extensive project experience in all core insurance processes: policy administration, property and casualty and life insurance, commercial liability, sales management, commissions, mortgages / home financing, motor insurance. Experience in migration projects. Field sales experience.
Extensive industry knowledge in banking (trained bank clerk). Projects in the areas of mortgages, home financing, factoring, lending, and securities trading.
Agile project management for projects of various sizes: from studies, analysis, and implementation through to production launch. The tasks included both internal project management (business and technical design, planning, employee management, coaching, and consulting) and external representation in governance committees, as well as implementation through to employee training.
Many years of experience as an application developer on IBM mainframes with the usual systems and development environments (MVS, IMS, CICS, DB2, Cobol, PL/1, etc.) and also in client-server environments (UNIX, Windows, Oracle, DB2, C, C++, Java, XML, PHP, VB, Clipper, etc.). Specialist in database design, programming, and administration (IMS, DB2, Oracle, mySQL, MS-Access), data modeling in the data warehouse ETL area with Cognos and PowerPlay. Many years of experience creating reports (Crystal Report, Cognos, MS-Access). Use of change management tools: Clear-Case, etc. in software development within large teams, including roll-out and deployment.
Many years of experience as a test manager in mainframe and client-server environments. Creation and implementation of many concepts emphasizing the need for testing from the initial phase through project maintenance and support. Use of, among others, the following tools: CONTINUUS (PT), Compuware (FILE-AID, XPEDITER, HIPERSTATION, ABEND-AID, DATA AGER), SQS (Kadett), HP/MERCURY tools (Load-Runner, Win-Runner, Test-Director), RATIONAL (ClearCase, ClearQuest).
Proficient in analytical methods (data modeling, structured analysis, object-oriented analysis, etc.), requirements specification, and test strategy development.
Training experience (data modeling, ISPF, analytical methods, IDE).

Test manager with more than 20 years of experience in planning, managing, and assuring the quality of complex IT projects, combined with more than one year of intensive, practical AI experience in productive software development. This combination is rare in AI testing: someone who has tested professionally for decades and knows AI systems from a development perspective understands both test methodology and the specific challenges of AI: non-deterministic behavior, result instability, drift, and bias.

Software developer by background; anyone who knows how software is created also knows where errors hide. I have defined and implemented quality gates, KPIs, and quality control processes in complex projects, most recently during 7 years at ERGO Lebensversicherung. In my own BrainStorm 2.0 project, I use AI-supported, automated test case generation (genTests) productively and develop daily with the Claude API (Anthropic), ChatGPT, and Gemini.
