Marco Rojas
Hola! My name is Marco and I’m currently a software engineer at Human Care Systems, where I work with NodeJs, Javascript, MongoDB, and Microservices. In my free time, I’m studying React, learning how to design data-intensive apps, as well as coding for microcontrollers. You can also find me working with Resilient Coders alumni, playing Apex legends or reading revolutionary tales. In the past, I worked with an agency, creating projects with REST APIs, Express.js, MongoDB, React-Native, React. I graduated from Benemérita Universidad Autónoma de Puebla (BUAP) as an Information Technology Engineer and worked for my university as a Systems Administrator. My university projects range from C++, Python, PHP, BASH, Java, OpenGL, Docker, and OpenStack. In my last year of college, I was also the local leader for the FreeCodeCamp community, and in partnership with Major League Hacking, we held events for the University’s tech community. Events included classes with Docker and Git 101, and workshops like Python for AI and Web Applications with NodeJs.
