Freelancer profile translated to English.

Description

I build AI systems for companies where knowledge, retrieval, and real-world constraints are crucial.

My background combines deep technical development with CTO-level product and system responsibility. From proprietary knowledge management systems and model infrastructure to enterprise copilots, regulated environments, and resilient decision support for management.

I work best where systems are complex, requirements are conflicting, and wrong decisions are costly. Especially when technical clarity is desired without consultant fluff.

Built an AI Lab from scratch and led it as Founder & CTO
Brought Enterprise AI copilots and retrieval systems into production using real company data
Commissioned by enterprise and regulated organizations for architecture, risk, and governance
Recognized by HPE for technical innovation in the enterprise AI space
Open-source contributions in Model Serving, Triton kernels, and retrieval systems
ACM publication on LLM training and system performance on AMD MI300A infrastructure

I help companies implement AI reliably on real enterprise data. From feasibility to architecture to operationalization.

My focus is on Enterprise AI, Knowledge Systems and Architectures, Retrieval/RAG, Document Intelligence, and the data layer behind productive AI systems. I work where AI initiatives often fail in practice: fragmented knowledge sources, weak retrieval quality, unclear target architecture, high costs, fragile PoCs, and governance not translated into technical reality.

I combine strategic positioning with technical depth and particularly enjoy working on questions such as:

- AI Readiness Reviews and technical due diligence
- Retrieval/RAG architecture and quality analysis
- Knowledge architectures for internal company data
- Document Intelligence, structured extraction, and data preparation
- Build-vs-buy decisions for AI stacks and knowledge platforms
- Translation of AI Governance / EU AI Act into technical controls and operating models
- Target state, prioritization, and roadmap for productive AI systems

Typical challenges I help with:
- unstructured or distributed company data
- poor answers despite existing models
- fragile AI/agent workflows
- high inference or processing costs
- lack of reliability, traceability, and ownership
- PoCs without a clear path to production

My profile is particularly suitable for companies that don't just want to "build something with AI," but need clarity on what works with real data, which architecture is viable, and how to turn it into a robust system.

Technical focus areas:
Enterprise AI, Retrieval, RAG, Knowledge Systems, Document Intelligence, structured extraction, Entity Linking, Multimodal Retrieval, Data Pipelines, AI Architecture, AI Governance, Vector Search, Late Interaction, Operationalizing AI systems.
