Front-End Engineer with 10+ years of experience building high-performance, scalable web applications for enterprise brands across Brazil and the US.
I specialize in modern e-commerce and product-led frontends — with deep expertise in Next.js, React, TypeScript, and Shopify. Over the past 5 years, I've worked extensively on large-scale storefronts, leading technology migrations from legacy stacks to Next.js, improving Core Web Vitals (LCP, CLS), and shipping critical product launches for brands like Arezzo, Arezzo USA, Bauducco, GOL, Unimed, and Bradesco.
My toolkit also includes Tailwind CSS, Storybook, Jest, Testing Library, Cypress, and Angular — with a strong focus on UI quality, component architecture, and frontend reliability.
Notable projects include the official Rio 2016 Olympics website and e-commerce platforms for Grupo Arezzo&Co (Brazil + US market via Shopify).
