About me


I’m a Computer Systems Engineer from the Autonomous University of Guadalajara where I’m working on my Thesis investigation to conclude the Computer Sciences Master’s degree. My investigation is about a solution of a 3D representation from an image on a haptic surface for blind, visually impaired or sighted people to allow perceive or enriching the perception of 2D images as a 3D representation generated by software that can be touched through the haptic interface.


            I currently work for HP in Guadalajara, México as Software Application Specialist focused mainly on the SAP/Unix replenishment platform for the Americas region.


            I’m interested on anything referred to computing, electronics or communication and I like to travel, do sports and cultural activities such as practice basketball, swimming, tennis and folkloric dance, watch TV and movies, reading and listening music among other things.
