Description

Looking for an expert who can transform your data into clear and actionable analyses?

As an Energy Studies Engineer at SNCF Réseau, I specialize in data analysis, modeling, and energy optimization. I assist my clients with processing complex data, automating calculations, developing decision-support tools, and creating maps and dashboards.

My areas of expertise include:

• Data analysis and processing (Python, SQL, Excel, MATLAB)

• Automation of calculations and reports

• Modeling and optimization of energy systems

• Mapping and geospatial analysis (QGIS)

• Data visualization and valorization

During my missions, I have worked with datasets of millions of records to identify energy optimization opportunities and support decision-making.

I prioritize robust, documented, and easily reusable solutions for my clients. Whether for a one-time need or a more ambitious project, I can support you from defining the requirement to final delivery.

Also available for short-term assignments: data cleaning, Excel/Python automation, MATLAB scripts, QGIS mapping.
