About me

Get to know my journey, experiences and skills

Who I am

I'm a Product Manager passionate about technology and creating solutions that positively impact people's lives. With solid experience in the entire product lifecycle, from discovery and validation to launch and iteration, I always seek excellence and innovation.

My approach is user-centered, data-driven and collaborative. I believe the best products are born from the union of deep understanding of user needs, clear strategic vision and flawless execution by multidisciplinary teams.

Outside of work, I'm a sports enthusiast, love to travel and I'm always learning something new, whether it's a new language or a new skill.

Beyond work

Sports & Data

I'm passionate about sports, especially basketball. That's where my love for numbers and statistics came from, which are fundamental parts of my professional background.

Basketball taught me to analyze data, identify patterns and make quick decisions based on evidence - skills I apply daily in Product Management.

The passion for statistics and data analysis started on the courts and became a powerful tool for understanding users and optimizing products.

Family & Pet

I'm a pet parent and have a shih tzu named Nina, the true joy of the house! She teaches me every day about patience, care and the importance of taking good care of those we love.

Nina is my faithful companion during studies, meetings and relaxation moments. She's always around when I'm working from home!
