I build thefrontend✦behind the frontend.

From interface to infrastructure — architecture, design systems, developer experience and the decisions behind products built to last.

01 / Selected work

The layers that make other frontend work possible.

I work where product, platform and people meet — turning complexity into foundations that teams can confidently build on.

01

Design systems as infrastructure

Foundations, tokens, components and tooling that help product teams move with more speed and consistency.

  • Web Components
  • Stencil
  • Tokens
  • DX
02

Modernizing without the rewrite

Evolving legacy applications progressively — protecting the business while improving the architecture underneath it.

  • Architecture
  • Legacy
  • Migration
  • Performance
03

Making frontend easier to build

Creating abstractions, conventions and tools so engineers can focus on the product instead of fighting the stack.

  • Tooling
  • Standards
  • Automation
  • Frontend
02 / What I care about

How I think matters as much as what I build.

01

Curiosity

Keep asking how things work — especially when nobody is waiting for the answer.

02

Fundamentals

Frameworks expire. What you learn about the browser, the product and people stays.

03

Decisions

Writing code is getting cheaper. Understanding what should exist remains expensive.

04

Leadership

Technical leadership is about multiplying people, not becoming the bottleneck.

03 / About

A career is not a straight line.

I grew up in Juruti, in the west of Pará, taking apart radios, TVs and anything else I could open. At 17, I walked away from the dream of working with technology. At 19, I started again.

Curiosity took me from Manaus to Joinville, back to frontend and, eventually, into technical leadership. Today I focus on the systems behind the screens — and on helping teams deliver without depending on a single person.
