About

I work as a Waste Engineer at Milgro, contributing to projects focused on sustainable resource use and waste reduction. With a background in public administration and economics, and currently pursuing an MSc in Industrial Ecology, I am building a broad understanding of how policy, innovation and systems thinking come together in sustainability practice. I enjoy working on circular economy challenges and always open to connecting with people and organisations driven by sustainability and environmental impact.
