Back to original languageAbout Leire
Hello! I'm Leire, a programmer and frontend developer specializing in UI/UX.
My journey began with web design and layout, evolving over the last seven years towards serverless frontend and fullstack development with Vue and Supabase. I combine user experience and programming to create complete applications from scratch, always focusing on UX, accessibility, security, and performance.
What I do:
- Transform designs into robust, accessible, and scalable interfaces, respecting the original design down to the pixel.
- Develop frontend from scratch with modern frameworks (usually Vue), with clean architecture and design patterns.
- Complex data visualizations with D3.js and Vega.js.
- Advanced CSS/SVG animations and microinteractions.
- Quality audits: performance, accessibility (WCAG), SEO, and best practices.
- Serverless fullstack development (Vue + Supabase)
- Creation of hybrid mobile apps with Nuxt + Capacitor.
- Zero unnecessary dependencies: I prioritize performance, stability, and maintainability.
Technical Stack:
- Frontend: Vue 3, Nuxt 3, TypeScript, Pinia
- UI/UX: Semantic HTML, CSS/SASS, BEM, Tailwind, Figma
- DataViz: D3.js, Vega.js
- Quality: Jest, Playwright, ESLint, Prettier, Lighthouse
- Architecture: Clean Code, Design Patterns
- Performance: SSR, SSG, PWA
- Fullstack: Supabase (auth, DB, edge functions)
- Mobile: Capacitor + Vue/Nuxt
