Building the future,
one product at a time.

I've spent the last 15+ years building startups in Brazil's vibrant tech ecosystem. From my first lines of Ruby code to leading engineering teams, I've been obsessed with turning ideas into products that people actually use.

As CTO and Co-Founder, I focus on the intersection of technical excellence and business impact. I believe the best products come from teams that care deeply about craft while staying laser-focused on solving real problems.

Currently exploring the next chapter—whether that's building something new, advising early-stage startups, or contributing to open source projects that make developers' lives better.
