About Romain

Freelance Data Engineer in Lyon, specializing in the design, deployment, and automation of data infrastructures.

With a Master's degree in Data Engineering, I have developed solid skills in database design, ETL/ELT, Cloud, orchestration, and RAG systems.

I first worked as a Data Analyst for the Ministry of National Education, where I developed automation solutions to increase productivity and limit errors. Subsequently, I held the position of Research Engineer for an organization conducting research in social sciences, where I provided my expertise in data analysis.

My goal: to help companies make their data flows reliable and leverage their business information through simple, documented, and maintainable solutions.
