Back to original languageAbout Martin
I am a data engineer specializing in Python, SQL, and PySpark, with experience in demanding industrial environments.
Specifically, I help teams make their data usable and reliable by building transformation pipelines, structuring datasets, and improving data quality.
At Airbus, I worked on complex data issues related to configuration management, with challenges in traceability, consistency, and availability for various business uses.
I can assist with:
- Data pipeline development (Python / PySpark / SQL)
- Data transformation and structuring (ETL)
- Data quality analysis and problem-solving
- Providing datasets for analysis or reporting
- Supporting business teams in understanding data
I prefer remote assignments, with the possibility of on-site presence in Toulouse if needed.
