Summary
👤
SeniorLeonardo Damasceno is a Senior Software Engineer from Rio de Janeiro with nine years of experience building scalable, user-centric frontends primarily using React and TypeScript. He specializes in microfrontend architectures and has practical experience across web and mobile (React Native), complemented by backend work in Node.js/Express and cloud/DevOps exposure with AWS and Terraform. Leonardo has driven features at large consumer platforms like Mercado Livre and Gympass, where he implemented Module Federation, GraphQL integrations, and contributed to design systems that improved cross-team velocity. He pairs hands-on implementation with product-focused delivery—organizing releases, monitoring performance, and aligning engineering work with business goals. Notably, he began his career improving processes at small teams (introducing Docker and testing) and has a track record of translating that operational mindset into more reliable, modular systems at scale.
