About Grégoire

During my final internship as a Software Engineer at NRG Consulting in Madrid, I delved into the complexity of energy markets and networks. But my true added value lies in my ability to bridge the gap between these business challenges in energy trading and their technical implementation.

My profile is dual: I understand the mechanics of trading, and I build the tools to exploit them.

As a (Data & Software) engineer, I design and deploy the architectures that support strategic decision-making:

⚙️ Data Engineering & Modeling: Creation of robust data models and development of pipelines (ETL) capable of retrieving, cleaning, and processing information massively (APIs, databases) in real-time.

📈 Optimization & Trading: Development and implementation of constrained optimization algorithms (e.g., MILP, integration of BESS storage models) to maximize the profitability of trading positions in different markets (Day-ahead, Intraday, etc.).

🚀 Automation & Software: Creation of reliable software and internal tools to automate time-consuming tasks, ensure data reliability, and free up analysis time.

Pragmatic, I prioritize concrete impact; I design reliable and high-performing technical solutions (Python, SQL, Next.js/TS) that generate direct ROI and provide an edge in the markets.
