Senior full-stack engineer | Brazil

Thoughtful engineering for ambitious digital products.

I'm a Brazil-based senior full-stack engineer, available for focused remote engagements and long-term work.

I build software, help teams solve difficult engineering problems, and work across the product lifecycle.

A little about my work

About

I have been working as a professional in technology and software engineering since 2008. I always like to work with honesty, punctuality, and clarity; and, of course, I expect the same from my clients.

As a senior full-stack engineer based in Brazil, I work across the entire product lifecycle—from custom software and web or mobile applications to AI development, cloud architecture, system integrations, and commerce platforms. I also support teams through technical advisory, ongoing development, maintenance, and support.
