Frontend Developer | React · TypeScript · Product-focused UI
I’m a frontend developer based in Barcelona with a background in graphic design and UI/UX.
I build responsive, accessible, and maintainable web applications, with a focus on reusable components, authentication flows, frontend architecture, testing, and thoughtful user experiences.
I also contribute across APIs, databases, real-time features, and containerized development workflows.
A focused frontend engineering project that demonstrates how a small but important product feature can be implemented with production-minded standards.
It includes typed forms, schema validation, API boundaries, accessible feedback, loading and error states, automated testing, mocked API scenarios, and CI checks.
Current focus: completing the authentication experience, expanding end-to-end and accessibility testing, and preparing a polished demo.
Stack: React, TypeScript, Vite, React Hook Form, Zod, TanStack Query, MSW, Vitest, Testing Library, Tailwind CSS, and GitHub Actions.
A collaborative full-stack application currently under active development.
The project is being used to build and document a production-inspired foundation for frontend architecture, authentication, databases, APIs, automated testing, and containerized development.
Current focus: authentication foundations, PostgreSQL integration, frontend–backend communication, Docker, testing, and project infrastructure.
Stack: React, TypeScript, Flask, PostgreSQL, Docker, TanStack Query, React Hook Form, Zod, Vitest, Testing Library, and MSW.
A full-stack, real-time team project developed at 42 Barcelona.
I contributed to frontend architecture, authentication and account flows, social features, direct messaging, real-time interactions, Docker and Nginx setup, internationalization, documentation, and reusable UI patterns.
Demonstrates: complex team collaboration, real-time state, protected application flows, API integration, responsive UI, and containerized development.
Stack: Next.js, React, TypeScript, Express, PostgreSQL, Prisma, Redis, Socket.IO, Docker, Nginx, Tailwind CSS, Storybook, and i18n.
