Al trabajar como freelance me acople a los horarios de la empresa, ya que tenia que estar ahi para checar el proceso de como se trabaja dentro de la empresa, habia momentos que los libros de java me generaban mas dudas que respuestas, ya que java aunque no habia vuelto a trabajar con el decidi retomarlo ya que era mas flexible, a mi parecer.
Java era o sigue siendo un lenguaje de programacion muy usado. Pero el sistema necesitaba algo visual.
Le habia comentado que usaramos PHP otro lenguaje de programacion web pero no se convencio ya que la persona encargada queria algo visual y con botones.
