Biography

Hello! I'm Gefferson. I'm a junior programmer who loves to build things with code. My first experience with programming was when I was 22 years old at university while I was studying electronic engineering, but it didn't last long: I was a big fan of video games, and one day I saw in a university lecture how to create a pacman video game with C++ and decided to do it. At first it was difficult for me because I did not understand the logic and syntax but after watching tutorials and asking friends for advice I was able to do it. Then I learned Matlab and I liked the graphs I made for the Linear and Discrete Control Systems course. On March 1, 2023, I graduated from the 18-week Beca Bicentenario Scholarship Intensive Bootcamp 3.0: Backend Developer and am looking for a full-time position where I can help a company achieve their goals.
