Senior Product Engineer — Platform & AI
I'm a Senior Product Engineer — Platform & AI. I design and build business applications, AI-powered products and the platforms behind them.
My work includes real-time voice training, conversational systems, document processing and internal workflows. I connect product requirements with software architecture, data integrations and day-to-day operations.
I started in state IT for North Rhine-Westphalia, moved into J2EE consulting, and later managed Citrix infrastructure for a municipal power plant.
From infrastructure I moved into product development, leading teams at McMakler and working on technical strategy as Lead Developer at a marketing agency.
Those roles gave me different views of the same problem: software has to work for the people building it, the people operating it, and the people relying on it.
I develop voice-based training tools for practicing customer conversations. The work connects real-time audio, configurable scenarios, session recordings and structured feedback.
Feedback needs to be traceable to what was actually said. I work on transcript-based evidence checks, evaluation rules and the flow from a live session to a reviewable result.
I build document workflows that combine automated classification and field extraction with human review. Users can inspect source evidence, correct suggestions and explicitly confirm the result.
The work covers the application and its document services: permissions, tenant isolation, background processing and handling concurrent changes. AI suggestions stay separate from confirmed information, and corrections remain part of the workflow.
I design internal applications that connect operational work across systems, including CRM data, document services and shared tools. The work starts with understanding the process and deciding which responsibilities belong in each service.
From there I work across the interface, APIs, data integration and operational tooling. Permissions, versioned changes and recoverable background jobs are part of the architecture, alongside monitoring and deployment.
