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.

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

Hi, I'm a freelancer with 8+ years of international experience as a Solution Architect, Data Engineer, and Python Developer, specializing in cloud platforms, scalable data infrastructures, and machine learning solutions.

Recently, I led the implementation of a modern Azure Databricks Data Lakehouse for a Swiss-German manufacturer, delivering a scalable analytics infrastructure with data governance frameworks, CI/CD pipelines, and LLM-powered analytics interfaces. I’ve worked with clients across various industries, delivering end-to-end data solutions.

Freelance projects I can help with:

- Building complete data platforms from scratch, tailored to your needs.

- Enhancing and upgrading legacy data systems for better performance and scalability.

- Establishing robust Databricks environments with proper governance and scalability.

- Developing machine learning and GenAI applications that integrate seamlessly with your data.

- Providing strategic guidance on how to kickstart your data initiatives or MVPs effectively.

Some of the technologies I work with:

Python, Spark, SQL, Terraform, Databricks, Airflow, Docker, MLflow, PyTorch, LangChain, SpaCy, Kafka, Bash, JavaScript, Fivetran, Flask, FastAPI, Power BI.

It currently works in two modes: fully automatic or with an interactive review where you can select which "main topics of the day" to include in your briefing. The result is a HTML document with summaries for each topic.
