Expert Data Platform GCP
I help companies build modern, scalable, and production-ready data platforms. Beyond building pipelines, I create robust industrial foundations designed to last and evolve. Whether starting from scratch or optimizing an existing stack, I maintain an approach focused on long-term platform operability and cost optimization.
My approach
I transform your raw data into strategic assets through several pillars:
- **End-to-end Data Architecture**: Complete design on GCP (BigQuery, Cloud Run, Pub/Sub), including infrastructure management.
- **Ingestion & Transformation**: Expertise in Python & SQL, mastery of several Modern Data Stack tools (Airbyte, dlt, dbt...) to ensure clean, actionable data throughout the chain, with business-needs-aligned modeling.
- **Focus on Operability**: Use of orchestrators (Airflow, Dagster...) for optimized runtimes, complete deployment automation with CI/CD, cost monitoring (FinOps management), and data governance (observability and data quality management). I ensure your data platform remains performant and cost-effective.
- **Governance and Quality**: Implementation of an observability system to guarantee solution reliability.
- **Strategic Support**: Documentation and training prepare your stack and teams for current and future data challenges (AI, machine learning...).
Feel free to contact me if you have needs requiring the transformation of your data into a growth lever!
