Jean-Mathieu is a Data Engineer at Datadog. As the first member of the Internal Analytics team, he designed and built data pipelines from scratch using Luigi, Spark, and Parquet files stored in S3. As the team grew, he worked on making the pipelines highly fault tolerant, reusable, and observable. He also deployed a scalable self-serve analytics platform throughout the organization for easy, accurate, and appropriate access to all internal data.
