This book is composed of snapshots of my professional experience as a female IT engineer and my email collections describing how I have become known as the Devil . . . . It is divided into seven parts in chronological order, consisting of independent episodes from my first job to my last job. The first five parts are my professional experience, focused on people who I met and various situations I had dealt with on the job. The 6th part reports how my situation has led to initiate the back position and what happened trying to join an organization supporting military IT operations (described as emails to my sister and some friends), how I got connected then trapped to the air against my will (described as emails). The 7th part is for moving into the global community joining a foreign-based company and some thoughts on harmony and happiness . . . . ?
