About

With over a decade of professional experience, I bring a robust combination of accounting expertise and sustainability leadership to drive impactful change. As a qualified Chartered Accountant through ICAS and former Global ESG Platform Manager at PwC, I am passionate about embedding sustainability into business strategies and fostering organisational growth aligned with global environmental goals. I thrive in dynamic, collaborative environments where I can contribute fresh perspectives and innovative solutions to complex challenges, ensuring alignment with shared values and a commitment to progress. Most recently at PwC, I led key global initiatives, including the flagship sustainability course for top global partners and the launch of the inaugural PwC Sustainability Academy. These efforts empowered teams across the organisation to prioritise ESG principles while aligning with client needs. Additionally, my role encompassed strategic communications, event coordination and data analysis using tools such as PowerBI, Tableau and the full Microsoft and Google suites, ensuring impactful delivery and measurable outcomes for global programmes and meaningful contributions to the wider PwC network.

    Trabajaba como auxiliar de conversación en el centro educativo infantil y primaria (CEIP) Paulo Freire, en Malaga ciudad.
