Message

At Circlr Labs, I launched a fintech and data company addressing the gap between consumer sustainability intent and purchasing behavior. I designed a proprietary sustainability metrics database and transaction-matching workflow that connects purchases to sustainability attributes.

As a Strategy & Sustainability Intern at Universal Music Group, I calculated and compiled Scope 1, 2, and 3 emissions and helped coordinate a company-wide sustainability summit. I also built an intranet site to make internal sustainability knowledge accessible to employees.

At FlowCarbon, I assessed demand for carbon-credit products and developed customer segmentation and product-positioning recommendations. At Metrodora Ventures, I synthesized clinical, regulatory, and market research into investment theses and supported diligence workstreams.
