What I'm looking for

I seek frontend or full-stack roles focused on modernizing interfaces, API integrations, clean architecture, and collaborative agile teams with growth opportunities.

I am a Frontend Developer with experience building modern B2B interfaces using React and TypeScript, focused on legacy system modernization, API integrations, and clean, performant UI. I have a foundation in full-stack development with Node.js and have delivered production sites and internal tools while working in agile teams.

Notable achievements include modernizing legacy corporate UIs to improve performance and usability, implementing Notion API integrations for interactive documentation, and building full-stack shipping and e-commerce tooling that integrates Shopify with Brazil's Correios. I work fluently in English and prioritize maintainable code, developer best practices, and user-centered design.
