About Rubén
Soy ingeniero de software. Lo que me mueve es entender un problema a fondo y construir la solución más sólida posible a partir de la tecnología disponible en ese momento.
Durante mi carrera he trabajado en sistemas donde la fiabilidad no es opcional: desde plataformas de procesamiento de datos satelitales para la Agencia Espacial Europea hasta software de control ferroviario en tiempo real en el departamento I+D de Siemens Mobility.
Hoy, lo que me tiene especialmente comprometido es la convergencia entre ingeniería de software e inteligencia artificial generativa: la integración de sistemas impulsados por IA en la lógica de negocio. Creo que es el siguiente gran salto en cómo construimos software y sistemas inteligentes, y quiero estar en el centro de ese cambio.
