Who I Am

Get to know me and my background

My Background

My name is Alfredo Gabriel, and technology is my great passion. As a computer scientist, I have dedicated myself since 2019 to developing applications that truly make a difference. The synergy between the robust backend of Spring Boot (Java) and the modern interface of Next.js (Typescript) has been the key to creating complete solutions, from scalability to user experience.

In this sense, I created stress scenarios for the applications I developed and for this there was a need to delve deeper into the study of GitOps, especially Kubernetes, in order to promote horizontal scalability for the application using the autoscaling concept offered by the environment, whether k8s, rancher or openshift. Thus, my skills and my passion for technology drive me to always seek to create creative solutions in different ways.
