Senior🎓
Top SchoolGuilherme Luiz is a Senior Software Engineer from Minas Gerais, Brazil with seven years of hands-on experience building performant, accessible web applications across frontend and backend stacks. He excels in the JavaScript ecosystem—React, TypeScript, Node.js—having architected multi-tenant platforms, a React design system with Storybook and CI/CD, and an onboarding system serving 1,300+ users that cut support tickets by 20%. Comfortable across product and growth functions, he runs A/B tests, integrates analytics and Hotjar feedback, and shapes priorities in agile and Shape Up processes. Guilherme pairs strong engineering craft (testing with Jest, RTL, Cypress) with pragmatic architecture work—modularizing monoliths and introducing cloud-ready patterns—to reduce developer overhead and boost delivery speed. He’s equally focused on mentorship through pair programming and meticulous code reviews, which helps teams set realistic, measurable goals. A former builder of large-scale Node.js crawlers and SSR performance refactors, he brings a data-informed mindset to both UX and backend reliability.
