Notas de trabajo sobre diseño, código y criterio.
Lo que aprendo entregando interfaces reales: arquitectura frontend, rendimiento, sistemas de diseño y trabajar con IA sin perder el hilo.
Frontend y rendimiento
Core Web Vitals, renderizado y el coste real de lo que construimos.
1 ARTÍCULOSistemas de diseño e IA
