I’m a senior frontend engineer based in Barcelona, focused on building customer-facing web applications with React, Next.js, and TypeScript. Over the last years, I’ve worked across travel, insurance, retail, and enterprise SaaS—delivering everything from reusable components and page delivery to testing, accessibility, and developer tooling. I transitioned into software engineering in 2019, bringing a strong analytical and process mindset from 14 years in global shipping operations. I care deeply about quality and maintainability: setting up modern architectures (like Turborepos and App Router), improving test coverage, and raising accessibility and performance metrics through disciplined CI/CD, reviews, and pair coding.…I’m a senior frontend engineer based in Barcelona, focused on building customer-facing web applications with React, Next.js, and TypeScript.
