SEEKING WORK | Remote | Based in Berlin, Germany

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.

If you have a data or ML/AI project in mind — or just want to explore possibilities — feel free to reach out. I’d be happy to have a chat!
