Introduction

Full stack development has become one of the most sought-after skills in the tech industry. As a full stack developer, you have the ability to work on both the frontend and backend of web applications, making you a versatile and valuable team member. With over 15 years of experience in full stack development, I'll share the essential knowledge and skills you need to succeed in this field.
