Joaco es de los mejores ingenieros que he conocido en mi carrera profesional. Tiene un nivel de profundidad y conocimiento de la materia increíble. Es el Senior que todos quisieran tener. Es capaz de manejar cualquier proyecto desde idea hasta ejecución; al igual de que es muy bueno liderando equipos de ingenieros y manejando sus tareas para cumplir adecuadamente y a tiempo con los proyectos. Recomiendo a Joaco a ojos cerrados para cualquier plaza técnica que desee.
