PROFILE
Arnaud
Arnaud Costes developed a scalable analytics export and data modeling stack for the betagouv/api-engagement repository, focusing on reliable data delivery and reporting accuracy. He implemented an end-to-end analytics export system to PostgreSQL, leveraging Docker and CI/CD pipelines for robust deployment and batch-driven processing. Using TypeScript and dbt, Arnaud designed new data marts and enhanced schema integrity, including concurrent indexing and backfill scripts to optimize time-based queries. His work standardized analytics event identifiers and improved build stability through dependency management and Terraform configuration. The solutions addressed business intelligence needs, reduced data latency, and provided a maintainable foundation for analytics workflows.
