What I'm looking for

I’m interested in applying my combination of technology, analytics, and problem solving to sustainability, climate, and carbon-related challenges.

At iFood, I apply data analysis to complex business problems, connecting business requirements with technical needs to support data-driven decision making. In my current role as a Fraud Prevention Specialist, I develop analyses and visualizations using Python, SQL, Databricks, and Tableau.

At Cielo, I supported data monetization with market insights across economic sectors and developed dashboards and visualizations using Tableau, Power BI, Python, and SQL.

My master's research at University of São Paulo focused on acoustic data visualization and Maui Software, an open-source framework for exploring soundscapes. I also researched deep learning models for classifying species from acoustic datasets and reinforcement learning for autonomous-vehicle driver models.

As President of Grupo Escoteiro Professora Inah de Mello, I led approximately 40 volunteers and supported strategic planning and organizational governance. I’m interested in applying my background in technology and analytics to sustainability, climate, and carbon-related challenges.
