Summary
👤
Senior🎓
Top SchoolFirmo Holanda is a front-end software engineer with 10+ years of technical experience and a strong focus on React and React Native, shipping mobile and web products for millions of users. He has modernized legacy codebases, built reusable design-system components, and launched apps with solid store ratings while handling localization and legal requirements for international markets. Comfortable across TypeScript, JavaScript and Ruby on Rails, he also brings a long history in infrastructure and automation—virtualizing servers and reducing ops costs before transitioning full-time to development. At Kinship and TradersClub he paired hands-on implementation with mentoring, analytics automation, and cross-team problem solving. Curious by nature, he started coding at 11 to automate social interactions and now channels that same curiosity into practical, user-focused engineering. Based in São Paulo, he’s open to front-end opportunities across the US, Canada and Europe.
