Sebastian Alejandro R.
Shopify & WordPress Developer | 90+ PageSpeed, Sites Built to Convert
I build WordPress and Shopify websites that sell, load fast, look clean, and are easy to manage without needing a developer every time something changes. Recent work took a client's site from 62 to 95 on desktop PageSpeed and 48 to 88 on mobile, a measurable fix, not just a fresh coat of paint. 3+ years across ecommerce stores, landing pages, and custom Elementor and Shopify Liquid builds. I specialize in entering existing projects, diagnosing what's actually broken, and fixing it fast instead of starting from zero. Claude Code is part of my daily workflow, so builds move quickly without sacrificing clean, maintainable code. Open to ongoing contracts and long-term partnerships. - Desarrollo sitios en WordPress y Shopify que venden, cargan rápido, se ven limpios y son fáciles de gestionar sin necesitar un desarrollador cada vez que algo cambia. En un proyecto reciente llevé el PageSpeed de escritorio de 62 a 95 y el de móvil de 48 a 88, una mejora medible, no solo un cambio de imagen. Más de 3 años de experiencia en ecommerce, landing pages y builds personalizados con Elementor y Shopify Liquid. Me especializo en entrar a proyectos existentes, diagnosticar qué está realmente fallando, y resolverlo rápido en vez de empezar de cero. Uso Claude Code a diario en mi flujo de trabajo, así que los builds avanzan rápido sin sacrificar código limpio y mantenible. Disponible para contratos continuos y relaciones a largo plazo.
