About

Professional summary

I am a carbon and sustainability consultant with a strong background in CSR strategy, carbon footprint assessments, and sustainability advisory across Europe. I have worked with SMEs, multinationals, public authorities, and SaaS teams to design practical roadmaps, implement action plans, and improve reporting and communication around climate impact.

I combine consulting, account management, and business development experience, which helps me translate sustainability goals into concrete operational and commercial outcomes. Over the years, I have delivered more than 60 carbon footprint assessments and contributed to sustainability strategies, workshops, webinars, and analytical tools.

I also have an entrepreneurial profile. I co-founded and helped run projects in tourism, bikepacking and personalized tourist city guides, where I developed partnerships, operations, and focused on growth and sales. These experiences strengthened my ability to build projects from scratch and work in fast-moving environments.

My professional path has taken me across France, Spain, the UK, Brazil, Japan, and other international contexts, and I am comfortable working in multicultural and cross-functional settings. I value adaptability, curiosity, performance, and teamwork, and I enjoy roles where I can combine strategy, communication, and execution.

Alongside consulting, I have experience in sales development, customer success, and content creation, including conference speaking on sustainability, adventure, and tourism. This gives me a broad perspective on how to engage stakeholders and communicate complex topics clearly.

I am particularly motivated by missions related to sustainability, climate action, business transformation, and purpose-driven growth. I bring energy, rigor, and a strong sense of commitment to every project I take on.
