ABOUT

How I approach frontend, architecture, and product.

I'm a Senior Frontend Engineer with 7+ years building scalable web applications across healthcare, finance, legal tech, e-commerce, and internal platforms. I focus on architecture, design systems, performance, and accessibility—and on shipping products that hold up in production.

Frontend architecture

Clear boundaries, feature-based structure, and patterns that keep large codebases shippable. I own decisions that affect long-term maintainability and team velocity.

Design systems & component libraries

Reusable components, tokens, and documentation that align product and engineering. I cut implementation time and keep quality bars consistent across squads.

Performance & accessibility

Core Web Vitals, WCAG 2.1, semantic HTML, and inclusive UX. I treat performance budgets and a11y as non-negotiables in production.

Product collaboration

I work closely with product and backend on API design, specs, and delivery. I help shape what we build and how it holds up in production—not just implement tickets.

Based in Brazil, I'm focused on international opportunities where I can bring this mix of technical depth, architecture thinking, and product mindset—especially remote senior frontend and tech lead roles.

CONTACT

Senior frontend roles, tech lead opportunities, and product-minded teams—I'm open to the right fit.

I'm interested in teams that care about architecture, design systems, and production-quality frontend. If you're hiring for a senior or lead frontend role—or building something that needs scalable UI—let's talk.
