Summary
👤
Senior🎓
Top SchoolGuilherme Ribeiro is a Senior Frontend Engineer based in Amsterdam with 10 years of experience building consumer-facing web applications using React, TypeScript, and Preact. He specializes in shipping reliable, production-grade UI and SDK work—most recently improving Adyen’s open-source Web SDK by shrinking merchant bundle sizes ~75% and scaling Playwright E2E coverage to 700+ cross-browser tests. Comfortable across product, design, and engineering, he has driven cross-platform API alignment with iOS, Android, Flutter and React Native teams and delivered integrations with Google, Apple, PayPal, Visa and Mastercard. An active open-source contributor, he’s fixed and hardened e2e suites and UI components in high-profile repos like adyen-web. Known for rapid, consistent feature delivery and pragmatic architecture changes, he often surfaces less obvious wins such as test infrastructure and tree-shaking improvements that materially reduce customer integration effort.
