About Me

👋 Hiya! I am John Skoubourdis and I am a web-developer. My passion is to create online web applications and teach others how to do so. I have more than 12 years of professional experience as a programmer and the last 3 years I am mainly focused on coaching small and medium size teams. You probably have heard of me from my famous open-source library named Grocery CRUD or my (not so famous) YouTube channel Happy Developers. If you like to learn more about me scroll down to see my bio.

My mission in one phrase

My mission is to create beautiful and professional websites and helping other people to do it so by sharing this knowledge.
