About Tristan

I design and implement scalable data solutions that transform raw data into actionable decisions.
From creating ETL/ELT pipelines (Python, Airflow, SQL, dbt) to data modeling and cloud infrastructure (GCP, BigQuery, Terraform, IAM, KMS), I develop reliable, secure, and high-performing systems.
An autonomous, rigorous, and curious professional, I am fully committed to each project to deliver concrete and impactful results, adapted to business and analytical needs.
