About

Gabriel Pfeffer

Here is a little background

Hello, I'm Gabe, and it's a pleasure to meet you! I embarked on an incredible journey, transitioning from a professional football player to an AWS Certified Cloud Practitioner Full Stack Developer. Driven by my need for dynamic environments and adaptability to changing circumstances, I find comfort in chaotic situations. Originally from Sao Paulo, Brazil, I relocated to Uruguay at the age of 9, granting me the ability to fluently communicate in Portuguese, Spanish, and English. You'll find me building full stack applications in my spare time. Collaboration comes naturally to me, and I excel in working seamlessly within a team. Your visit to my portfolio means a lot, and I appreciate your interest. Let's embark on this exciting journey together!
