I am Erwin Pratama, my job is to update articles on erwinpratama.com every day. I joined StackOverflow.com to learn about programming, such as HTML, JAVA, PHP, and others. I am a graduate of a school majoring in computer and network technology. For that I understand a little about computer science and networking. Then after graduating, I made the decision to create a website with the address https://erwinpratama.com
