Badalona, Catalonia · ES — open to remote (EU / UK timezones)
My live portfolio is hosted on GitHub Pages:
It covers what I work on, the stack I reach for, selected projects, and a short experience timeline.
- Building scalable React/TypeScript apps (8+ years, React 18, Vite, single-spa microfrontends).
- Leading large-scale migrations — owned a React 17 → 18 upgrade across multiple teams.
- Testing infrastructure with Jest + Playwright, accessibility to WCAG 2.1 AA.
- Embedding AI-augmented workflows (Claude Code, Cursor, GitHub Copilot) so the team compounds.
