Work

I'm on a mission to build intelligent, sustainable, and impactful products. Here's a summary of my work so far.

QuintoAndar

Senior Head of Product, 2025 - current

QuintoAndar is one of Latin America’s largest real estate technology companies, transforming how people buy, sell, and rent homes through digital-first, data-driven platforms. At QuintoAndar, I lead initiatives focused on AI-powered products across complex, high-stakes real estate transactions. My work centers on building intelligent platforms, driving operational efficiency, increasing trust and transparency, and applying Generative AI and automation to reshape end-to-end customer journeys at scale.

Lemon

Chief Product Officer, 2023 - 2025

Lemon is a climate tech startup that makes clean energy accessible — no solar panel installation, no upfront investment. Lemon connects individuals and businesses to local solar plants, driving distributed energy generation across Brazil. As CPO, I led the product organization end to end, defining product strategy and vision, structuring and scaling high-performing teams, and building intelligent, user-centered solutions that improved customer experience, operational efficiency, and business scalability.

Trybe

VP Product, 2020 - 2023 Director of Product Management, 2020 - 2023

At Trybe, a web development school with an income-share model, I built and led the Product, Design, and Research teams. I owned the end-to-end digital experience—from enrollment to job placement—delivering a hybrid learning platform that combined asynchronous content, live classes, and career support. As employee #30, I helped scale Trybe’s student base from 70 to 2,500 per year by launching solutions across the full user journey—from acquisition to financing and job placement.

Hekima

Co-founder & Product Lead, 2013 - 2020 Co-founder & Software Engineer, 2008 - 2013

While still in undergrad, I co-founded Hekima, an AI startup that developed end-to-end machine learning systems to help companies make better use of their data.

In Hekima’s early days, we built Zahpee Monitor, a social media AI platform designed for real-time processing and analysis of millions of posts. It featured a resilient infrastructure and supported analysts with advanced AI capabilities. We implemented models for sentiment classification, hierarchical topic clustering, geolocation inference from text, author influence ranking, and active learning to accelerate model training. Zahpee was used by major brands to detect crises, monitor perception shifts, and guide real-time communication—especially during high-volume events like the 2014 World Cup. As the company grew, I led the design of AI solutions for B2B clients tackling a wide range of business goals—assessing data readiness and co-designing solutions using techniques such as NLP, predictive modeling, and scalable ML architectures. I also led the development of a platform that automated the AI workflow, from data preparation to model design and deployment.

Our solutions were adopted by some of Brazil’s largest enterprises, and in 2020, Hekima was acquired by iFood, Latin America’s leading food delivery company.
