    Hi, I'm **Samuel Lima Braz**, a Computer Engineering student at UNIFEI (Universidade Federal de Itajubá)

    My programming journey began in 2018 with C during my technical course in Industrial Automation. 
    I entered the world of Computer Vision in 2023 when I joined Black Bee Drones, the first autonomous
