About Joan

With 17 years of experience in the energy sector, I have acquired in-depth expertise in customer operations, billing, and business tool management. My career at Altergaz and Eni has allowed me to hold various roles and contribute to high-impact strategic projects.

What I master perfectly:

• Billing processes: Data models, pricing implementation, tax management, and all necessary steps to ensure accurate and compliant billing.
• Business tools: Recognized expertise in SAP IS-U and SAP CRM, complemented by solid experience in SalesForce and the Office suite.
• Distributor flow management: Integration, monitoring, and optimization of flows, as well as managing replication between different IT systems.

My strengths:

• In-depth analytical skills, essential for solving complex problems and optimizing processes.
• Advanced mastery of technological tools, enabling me to manage technical projects and collaborate effectively with IT teams.
• Natural curiosity and a passion for continuous learning: I am constantly seeking new skills, innovative solutions, and ways to expand my expertise.

Throughout my career, I have managed external service providers, overseen the evolution of business tools from requirements gathering to production, and ensured the quality of system integration. This drive to learn and progress allows me to approach each challenge with openness and enthusiasm.

Passionate about challenges and innovations in the energy sector, I am always ready to discuss, share ideas, or collaborate on ambitious projects.
