What I'm looking for

I'm looking to build accessible, high-performance product interfaces and scalable design systems, with opportunities to apply Next.js, measurable performance work, and AI-assisted workflows across collaborative teams.

At Compass UOL, I build enterprise React and Next.js interfaces for Burger King, Starbucks, Subway, and Popeyes. I designed an accessible component library that standardized a four-brand design system, reducing development time by approximately 30% and accelerating feature delivery by approximately 25%.

I've spent over four years building and maintaining Brazil's nationwide PNLD education platform for the Federal Government, where availability and correctness are essential. Across client projects, I've delivered resilient React interfaces, REST API integrations, and reusable components that increased user engagement by 15%.

I work with Next.js App Router, TypeScript, design systems, Core Web Vitals, and applied AI workflows using Claude Code and Figma MCP to shorten design-to-production loops.
