I'm looking for a fully remote Frontend Developer role where I can work with React or Angular on products that actually matter. I enjoy collaborative teams, clean code, and projects where the frontend is taken seriously — not just an afterthought. Relocating to Bilbao, Spain in August 2026, so open to European or international companies comfortable with async work.

BrazilWhat I'm looking for
I’m a Senior Frontend Engineer with 5+ years building and scaling business-critical web architectures for massive audiences. At Santander Brazil, I delivered microfrontend solutions that serve 1M+ daily users and drove a 40% increase in customer conversion.
I specialize in Angular, React, Microfrontends, SSR, and cross-platform mobile/web integration. I led an end-to-end microcredit offer acceptance journey into the Santander mobile app via WebView and native bridge architecture, strengthening transaction security while opening a new acquisition channel.
I also architected and delivered a unified microfrontend for Santander’s portal home page—replacing separate mobile and web codebases—eliminating duplication and improving SEO/accessibility scores from 25% to 75%+ (reaching 100% on key metrics) through semantic HTML improvements. I’ve integrated frontend applications with enterprise CMS platforms, worked across mobile/backend/platform teams, and use tools like GitHub Copilot and Devin for AI-assisted development and code review.
