_{Badalona, Catalonia · ES — open to remote (EU / UK timezones)}

My live portfolio is hosted on GitHub Pages:

→ ibsenjg.github.io

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.
