About

I like software that earns its place in the business.

I build SaaS products, business systems and AI integrations for teams that need the product to work beyond the demo.

Profile

I am a full-stack product engineer based in Brazil. I build SaaS products, business systems and third-party integrations with a practical bias toward shipping.

I have delivered more than five products, including two SaaS products live with real users, across CRM, e-commerce, fitness and real estate.

My work spans product thinking, UX, frontend, backend, data modeling, APIs, cloud infrastructure and post-launch maintenance.

Before focusing fully on software engineering, I worked with technical support, marketing and business operations. That background helps me understand users, sales processes and the operational pressure behind a feature request.

I am currently looking for a remote international opportunity where I can contribute as a full-stack or product engineer, work with a strong team and take on larger technical challenges.

How I work

  • Understand the operation before drawing the screen.
  • Prefer clear systems over unnecessary complexity.
  • Treat integrations and failure states as part of the product.
  • Leave decisions clear enough for the next person.
  • Move fast without making the system fragile.
  • Explain technical choices in business language.
