La intensión de este Blog es poder documentar y compartir el conocimiento que a través del tiempo se me ha atravesado en este Tao de IT. 

Siempre dicen que es bueno leer pero he aprendido que se debe construir algo para que sea beneficioso ese conocimiento adquirido, ya que de otra manera solo se queda como un dato anecdótico sin mayor utilidad.

En esta época es fácil encontrar demasiada información y lleva mas tiempo leer toda esa información. Así que por sugerencia, me agrado la idea crear este Blog para compartir los temas de mi interés y a la vez contribuir con mi experiencia.

Los temas principalmente estarán enfocados a ITManagement Finanzas debido a mi carrera profesional como Ing. en Sistemas Cmputacionales.
