Hi! I’m David Willi. I learned English by myself with the internet, which provided me with the skills, resources and creative solutions to help you master English with online tools. I love talking about countries and culture, music or tech trends such as AI. I also currently am a Computer Science student at a American university and have experience with college applications and interviews to help you reach your academic goals. 🇧🇷 For Portuguese speakers: Podemos usar o português para dúvidas, explicações e ajuda nesses primeiros passos. Te ajudo em cada processo até a fluência!
