A more natural version of this might be something like the following:
"Hello everybody. I will start by introducing myself. I am Ramin Mahpour. I’m a web developer with 13 years of experience. It’s a pleasure to meet you all. I am here to answer your questions and today I will be available for six hours.
Before you start asking questions, let me say something about IT and technology. Traditionally, people thought a man must work outside for many hours every day. In the modern world, people don’t want to work outside, and technology has completely changed how we think. For example, the workplace is now accessible to a more diverse workforce."
