Welcome!My name is Giovanni Marques, I'm a back-end developer with a passion for technology. My journey began in the front-end, where I had my first contacts with HTML, CSS, JavaScript and React. My curiosity to understand where the data presented in the interfaces came from led me to explore the back-end, and I soon realized that this was the area I really wanted to pursue as a career.As a back-end developer, I realized how much I enjoyed studying concepts such as development principles and software architectures, which solidified my choice.
