Senior🎓
Top SchoolRaphael Cousin is a Research Engineer and data-savvy practitioner with nine years of experience building cloud-native data platforms, ML systems and scalable production pipelines across startups, public utilities and academia. He has led teams and shipped end-to-end solutions—from migrating ETL to dbt and operating thousands of Airflow DAGs on Kubernetes to deploying MLOps and LLM/RAG services—demonstrating strong cross-functional delivery in supply chain, water management and recommender systems. Comfortable across AWS, GCP and Azure, Raphael blends deep mathematical training with hands-on software engineering (Python, Spark, Kafka, Terraform) to optimize performance, cost and governance at scale. He teaches practical data science at Sorbonne University, sharing industry-grade workflows (Git, Docker, reproducible environments) with graduate students while continuing freelance engagements that span cloud migration, DataOps and ML deployment. Notably, he scaled a SaaS data platform from hundreds to over a million items and routinely manages pipelines processing hundreds of millions of integration rows daily.
