Senior Product Manager · Rio de Janeiro

I cut churn and get recurring revenue growing again.

Over 10 years in B2B and B2C digital products, in healthcare, platforms and SaaS. I specialize in activation, retention and churn reduction, almost always in regulated, technically complex contexts.

Whitebook

Clinical decision app with over 65% share among physicians in Brazil and 220k monthly active users. Nearly 3 years at PEBMED, part of the Afya group, where I joined as a Product Designer and became a PM. I led growth from 85k to 115k subscribers in 2019, roughly R$1.47 million in incremental MRR. The medical community started as an MVP inside it and became its own product.

I started in Design, became a Product Manager, and never let go of the UX sensibility.

Senior Product Manager with over 10 years in B2B and B2C digital products: I entered tech in 2013, have worked in product since 2015 (first as a Product Owner and designer), and have been a PM formally since 2019.

I specialize in activation, retention and churn reduction, with a secondary focus on platforms, APIs and integrations. I've worked at healthtech and B2B SaaS scale-ups (Afya/PEBMED, Unico IDtech, Huna, Wehandle and 3DGym), almost always in regulated, technically complex contexts.

Benchmark results: at Whitebook, growth from 85k to 115k subscribers in 2019, representing roughly R$1.47 million in incremental MRR; at 3DGym, churn from 17% to 7.8% with ~R$348k/year in recurring revenue recovered and break-even hit 2 months ahead of schedule.

Today I'm Product & Growth Lead at FoundersPM, a healthtech product consultant at PoliHealth, and a Product Management mentor and instructor at Tera, where I've mentored over 3,000 professionals, from beginners to executives.

I hold an MBA in Business Intelligence and a bachelor's degree in Graphic Design, which gives me a practical UX lens when prioritizing and designing products, from user research all the way to delivery.
