“Build it, break it, fix it better!” is something I often say. I am a seasoned cybersecurity professional who has been in the field for more than a decade. I have a formal education in computer science and extensive experience in security evaluation, security research, and building secure products across multiple verticals. In recent years, my focus has been AppSec, where I’m working on bridging the gap between security and engineering teams, making security an interesting and enjoyable aspect of everyone’s life. Outside of the cyber world, I have an active lifestyle and enjoy sports. Currently, I am re-introducing music into my life, as it is the space where, aside from hacking, I express my creativity the best.
