👤
Senior🎓
Top SchoolRenato Freire is a Full Stack Engineer based in São Paulo with a decade-long focus on JavaScript/TypeScript front-end engineering and eight years of professional experience building React and React Native products. He has a measurable track record: launched a React Native MVP that onboarded 72,000 users and generated over 1M BRL in sales, improved Lighthouse accessibility/SEO scores by 10+ points, and cut sales-team workload by 30% through Design System–aligned components. Comfortable across the stack, Renato has led migrations (Vue→React, JS→TS), optimized app performance (reducing launch time from 3s to 1s), and raised test coverage with Jest and Cypress. He also brings teaching and tooling experience—updating curricula, mentoring teams, and streamlining CI with GitHub Actions to cut infrastructure time by half. This mix of product impact, accessibility expertise, and developer tooling makes him reliable at turning UX and engineering improvements into measurable business results.
