Description

If your goal is to move from AI strategy to actual implementation, you don’t need more concepts – you need a SOLID DATA FOUNDATION.

That’s where I come in.

As a freelance Data & AI Engineer, I build scalable data platforms and prepare organizations for real-world AI use cases – from advanced analytics to production-ready ML and LLM applications.

I’m typically brought in when:

data platforms stop scaling or become overly complex
AI initiatives are stuck between concept and production
data foundations aren’t ready for advanced analytics or LLM use cases
performance, cost or reliability become critical issues

What I deliver:

Modern data platforms (Lakehouse, Medallion, Data Vault 2.0)
Scalable pipelines (Spark, Kafka, cloud-native architectures)
AI-ready foundations (RAG, vector databases, MLOps)
Migration & modernization (Azure, SAP, legacy systems)
Architecture decisions that still hold 2–3 years from now

I combine strong data engineering fundamentals with hands-on AI experience – not to experiment, but to build systems that actually run in production.

I don’t join projects to add capacity. I join to solve problems.
