David Macías Alejandro

Jose Luis García puede ser recomendado por muchas cosas, pero sobre todo por su integridad y profesionalidad. Destacaría tambien su facilidad de integrarse en apenas horas dentro de nuestro equipo, adaptándose rápidamente a nuestro workflow diario. Trabajar con él nos ha permitido dar un salto de escalabilidad importante, y completar vacíos en administración de sistemas que no teníamos cubiertos hasta ahora.

Javier Miguel

Es una persona con gran capacidad técnica, que sabe encontrar las causas de los problemas y ponerles solución, así como crear nuevas infraestructuras para plataformas de gran carga de proceso. Un placer trabajar con el.
