  • B2B and B2C training (Databird, Jedha, Blent): I train your teams on technologies and best practices, particularly the implementation of DBT and the management of layered transformations.
Technologies I have worked with:
  • Data Warehouse: Snowflake, GCP, AWS, Databricks

  • ETL/ELT: Fivetran, Airbyte, Python
  • Visualization: Metabase, Tableau, Looker
➡️ If your project involves a tool or technology not on my list, please feel free to contact me, as I am always interested in discovering new technologies.

Caroline assisted Zelty in setting up their data stack. Being novices in this area, she guided us effectively, adapting to our constraints and pace. The result met our expectations: a validated PoC and a great deal of learning for the future. We will undoubtedly call on Caroline again if the opportunity arises.

Reviewed on 10/3/2024

Caroline supported us for seven months on a mission to migrate our ETLs to DBT. She integrated perfectly into the team, quickly mastered our technical stack, and implemented good coding practices. The architecture she designed was deployed rapidly, and she managed to migrate everything while considerably improving the business logic of the various models. Furthermore, Caroline showed great pedagogical skills with the analytics teams, enabling them to adopt the tools, code, and new standards established. I highly recommend her.
