Hey there, I’m a husband and parent from Rio de Janeiro, now living in Amsterdam.

At Shopify, I’m a staff frontend developer working on checkout and Shop Pay. Alongside building scalable software with JavaScript and TypeScript, I mentor developers and look for ways to make development processes clearer and easier to work with.

I’m currently interested in agentic development and how to design processes and systems around it. I focus on using agents to their full potential while shipping software that meets a high standard of quality.

Outside work, I love to cycle, cook and travel.

The work

Since
2010.

I’ve spent most of my career in commerce, building deep expertise in checkout and conversion while creating shared tools and mentoring developers.
