Description

Looking for a Data Engineer to industrialize your data platform? You've come to the right place.

I help companies (startups, SMEs, large enterprises) design, modernize, and optimize their Data Platforms. My approach is centered on three pillars: data reliability, industrial automation, and strict control of infrastructure costs (FinOps).

I am certified in Snowflake Hands On Essentials.

I manage the implementation of your modern Data Platform, Cloud or On-premise:

Design and architecture of your Data Platform (ingestion, transformation, delivery)
Development of ETL/ELT pipelines (Airflow, DBT, Talend, Spark)
Setup and optimization of your Snowflake Data Warehouse (FinOps, RBAC), Data Lake
Setup of the CI/CD pipeline
Large-scale big data processing (Python, PySpark, SQL)
Creation of decision-making dashboards (Power BI, Tableau)
Migration to a modern cloud Data Stack (AWS, GCP)

Concrete achievements and impacts:

30% reduction in Cloud infrastructure costs through Snowflake architecture optimization.
Deployment of automated pipelines processing transactional flows of over 100,000 records with high availability.
Drastic acceleration of access time to key indicators (from 24 hours to less than 5 minutes).
Automation of complex reporting, reducing manual preparation time for business teams by 70%.

Why work with me?

I provide a weekly report detailing all tasks performed, any blockers, and next steps. You maintain full control over your project's progress, with complete transparency.

Autonomous, rigorous, and accustomed to collaborating directly with business teams, I quickly adapt to your technical stack and business challenges.
