About Tim

AI Architecture & Enterprise Integration for SMEs

I bridge the gap for companies between established legacy systems and future-proof, autonomous AI architectures. As an experienced IT leader, I combine deep technical system understanding with strategic business value.

My Focus & Expertise:

Agentic AI & Workflows: Conception and data-sovereign integration of intelligent AI agents into existing enterprise architectures.

Enterprise Integration (SAP/Legacy): Seamless connection of modern AI components to complex core systems and established database structures.

Agile Project Leadership: Crisis-tested leadership of complex digitalization projects (Scrum, Kanban, Hybrid) with budgets in the millions.

My introductory offer on Malt — The 3-Day AI Readiness & Cost Audit:
Are you planning AI automations but are concerned about data sovereignty (on-premise) or uncontrolled API costs? Within 3 days, I will analyze your existing infrastructure and your core processes. You will receive a crystal-clear roadmap including a Data Quality Score and a hard ROI assessment for your planned AI initiatives.

Ready for clean data and real automation? Write to me here on Malt for a non-binding initial check on an equal footing.

Experience

    Unit Lead and Senior Manager
    DIGITAL AND IT
    October 2016 - Today (9 years and 10 months)
    Saarbrücken, Germany
    As Unit Lead and Senior Manager, I lead an international, distributed consulting unit with currently seven experienced consultants. Together, we support our clients in successfully implementing digitalization projects – pragmatically, solution-oriented, and always on an equal footing.

    In my leadership, I place great importance on empathy, trust, and genuine appreciation. It is important to me that my team feels comfortable, can contribute its strengths, and is given space to develop further. I actively support my employees – through exchange, regular feedback, and the promotion of individual skills.

    I work agilely – not as a buzzword, but out of conviction. Transparency, iterative steps, clear communication, and an open error culture are fundamental components of good collaboration for me. I live these principles both within the team and in our client projects.

    Together, we ensure that our clients achieve real progress – through practical solutions, good teamwork, and reliable collaboration.

  • Reinwerk Systems
    Founder
    DIGITAL AND IT
    April 2026 - Today (4 months)
    Merzig, Germany
    Reinwerk Systems closes the critical gap between visionary AI initiatives and the established IT reality of German SMEs. As a strategic partner and technical architect, I conceive and integrate data-sovereign, autonomous AI systems (Agentic AI) directly into complex enterprise infrastructures and SAP landscapes.

    Focus and Operational Responsibility:
    AI Sovereignty & On-Premise Architectures:
    Conception, orchestration, and deployment of LLM infrastructures and AI agents that run 100% locally (Docker, Private Cloud) – absolutely GDPR-compliant.
    SAP & Legacy Data Integration: Development of automated pipelines for semantic deduplication, normalization, and cleansing of heterogeneous master data to prepare legacy systems for RAG applications without errors.

    AI Cost Control (Token Analytics): Implementation of governance structures and API cost tracking models to systematically prevent uncontrolled runtime expenses in complex agentic workflows.

    Agile Leadership & Value Engineering: Management of business-critical digitalization projects at C-level and CTO level with a clear focus on measurable business ROI rather than mere technology experiments.
