Software Engineer · Brazil

I build high-trust experiences for complex products.

Frontend engineer focused on React, TypeScript, architecture, and real-time financial experiences. I care about the point where product clarity, performance, and technical decisions become user trust.

Who I am

I’m a frontend engineer working at the intersection of product, architecture, and user experience. Today I build investment and trading flows used by thousands of people, supporting more than $620M in monthly transaction volume and more than 200k orders a month.

Over time, working on financial products taught me that frontend is not just a visual layer. It is where business rules, state, real-time data, performance, and trust come together in the user experience.

That context changed the way I think about engineering. I started looking less at isolated components and more at systems: how a state decision affects an entire flow, how an interface communicates risk, how architecture reduces ambiguity, and how technical quality sustains speed over time.

This mindset has shaped my work on trading experiences, real-time data, state modernization, design systems, and AI tools applied to software development. I use AI as engineering leverage, not as a shortcut, keeping standards, review, and architecture in human hands.

Beyond building software, I share what I learn about frontend, architecture, AI, and career. I want to help other developers grow with more clarity, not by pretending there is a perfect path, but by making the thinking behind good engineering easier to see.
