From developer to Solution Architect to Product Owner at one of Europe's leading manufacturers of driverless transport systems. Responsible for product vision, roadmap, and the bridge between the business unit and development. Architectural concepts are developed and further refined and decided in close cooperation with the chief architect. Figma for Design Systems and Prototyping, .NET, Angular, SQL Server.

As part of a group-wide Active Directory migration from NT 4.0 to Windows 2000 — including the consolidation of all subsidiaries into a unified directory — the enterprise software used lacked a crucial feature: flexible scheduling. Development of a web application for complete migration management and a lean Delphi tool without runtime dependencies for automated compliance checking on migrated PCs. Personal execution of the migration on-site at several subsidiaries.

Years later, a second tool followed: an offline inventory and remote execution system for PCs that could not reach the central inventory server. Inventory data could be transmitted via email, USB, or other means — server-defined command-line commands enabled remote actions such as automated trojan removal. The tool is still executed on every client PC of the group at startup.

Development of an innovative call center tool with a graphical administration interface (in Delphi) for the visual design of arbitrarily complex conversation flows — similar to a word processor, but for conversation logic. The agent view ran as a web application based on .NET 1 Beta — at a time when web applications were still the exception. Including a fully implemented softphone directly in the application.

Technical highlight: A dynamic schema management that can extend entities with arbitrary attributes at runtime — without performance loss. Instead of classic key-value pairs, the database schema is physically adapted at runtime. A physical view automatically generates the SQL statements, a logical view combines OOB, global, and tenant-specific attributes into a unified view. Each tenant gets its own columns — with identical performance and full filter and sort comfort as with standard fields.

The software was only sold four times — but is still running productively at two customers after over 25 years. Fun fact: During this period, the telephone system was replaced four times at one customer and reconnected each time. The software was not. And it doesn't stand still: most recently expanded with GDPR compliance and Exchange 365 integration.
