Olivier D.

I architect and build production-grade data platforms for companies that have outgrown spreadsheets and fragile BI. I specialize in designing full-stack Snowflake + dbt + Airflow systems that power executive and investor-level reporting. For the past 6+ years, I’ve owned end-to-end data architecture — from ingestion and warehouse design to modeling, orchestration, and executive reporting. I don’t just write queries — I build the full system. Recent platform builds • KnowV8 (US-based analytics company) – Sole architect and engineer of a fully automated Snowflake + dbt + Airflow stack powering daily production reporting. Designed ingestion workflows, dimensional models, and reporting structures used for executive decision-making. • Optium Capital (US PE-backed firm) – Designed and built a Snowflake-based analytics platform integrating multiple data sources, enabling governed reporting and replacing spreadsheet-driven processes. • RTL (Enterprise Media Company) – Integrated a new large-scale data source into an existing Snowflake + dbt + Airflow ecosystem. Worked with datasets exceeding 100M–1B+ rows, ensuring scalability and data integrity. ⸻ What I help clients with • Architecting scalable Snowflake-based data warehouses • Designing clean, maintainable dbt transformation layers • Building reliable Airflow pipelines for production workflows • Replacing Excel-based reporting with structured BI • Creating consistent, auditable numbers for leadership teams • Connecting APIs and external data sources into modern data stacks ⸻ Core stack Python, SQL, Snowflake, dbt, Airflow, AWS/S3, Tableau, Power BI, Azure ⸻ If you need someone who can both design the architecture and implement it end-to-end — I’m that person.
