Available to hire
I am Abraham Navarro, a Senior Frontend Engineer based in Buenos Aires, Argentina, with 5+ years of experience building production-grade web applications using React, TypeScript, and Next.js. I contributed to high-traffic platforms at Banco Galicia (via Baufest), including one of Argentina’s first mortgage origination products in years, built from scratch.
I specialize in clean architecture, reusable components, and UI performance. I lead frontend work on banking products, create shared component libraries to speed up delivery, and leverage AI-assisted development with Cursor and Claude to move faster while maintaining code quality.
