Jorge - Essence Ineractive Center, S.L.


Rubén es un excelente desarrollador con buenos conocimientos sobre arquitecturas distirbuidas de microservicios y technologías que se utilizan para el desarrollo de productos de alta disponibilidad en la Nube. No sólo ha conseguido incorporarse a un proyecto complejo, desde el punto de vista de arquitectura, sino que ha demostrado sus capacidades en plazo muy breve de tiempo, demostrando así sus capacidades para el trabajo en equipo, la colaboración y una comunicación efectiva. Volveremos a trabajar con el en el futuro, creo que esa es la mejor carta de presentación.
