Data & AI engineer, 9+ years. I design, build, and review data platforms and ML/AI systems end to end — lakehouses, ML pipelines, RAG, agents, cloud infrastructure, rapid PoCs. I own retrieval quality and data-readiness for RAG and agent systems — the data plumbing underneath the LLM call, plus the evals and guardrails on top.

I also advise engineering teams on AI-assisted development workflows.

Client references available.

Freelance data & AI engineer with 9+ years of experience. I've worked with early-stage startups and established manufacturers across Germany, Switzerland, the US, and Canada. I design and build data platforms, ML/AI systems, and the infrastructure around them - end to end.

Most recently, I worked with a NYC startup on system design for their data architecture, built production data pipelines in Rust, set up cloud infrastructure with Pulumi, and implemented idempotent automated workflows with Prefect. Before that, I led the implementation of an Azure Databricks lakehouse for a Swiss-German manufacturer, including data governance, CI/CD pipelines, and LLM-powered analytics interfaces.

What I can help with:

  - Data platform architecture and pipeline development
  - ML/AI systems: RAG, agents, fine-tuning, evaluation pipelines
  - Cloud infrastructure and orchestration (Azure, GCP)
  - Proof-of-concepts and MVPs — I favor iterative approaches, starting focused and building from there

Client references available upon request.

If you have a data, AI, or infrastructure project in mind or just want to explore possibilities - feel free to reach out. I'd be happy to have a chat!
