Back to original languageAbout Yanis
Currently pursuing a dual engineering degree at École des Ponts et Chaussées and École Polytechnique (after preparatory classes at Saint-Louis), I assist companies in analyzing their data and automating their decision-making tools.
I offer my skills for quantitative engineering and data analysis missions, with a strong focus on issues related to industry, logistics, and energy markets.
Specifically, I work on three types of subjects:
- Quantitative and financial modeling: time series manipulation, backtesting, and risk analysis in Python (Pandas, NumPy).
- Data structuring: complex queries and database management (SQL, PostgreSQL, PostGIS).
- Internal tool automation: development in Excel/VBA to digitize operational processes and ensure the reliability of your teams' reporting.
I am accustomed to combining mathematical rigor with concrete business challenges. Feel free to contact me to explain your needs or current project, I would be delighted to discuss it with you.
