Hello! My name is Jeferson Santos. I have a bachelor’s degree in Information Technology and have been investing in stocks, real estate funds, and fixed-income securities for 6 years. I started with R$100, and by applying analysis and discipline, I managed to grow my net worth by more than 80%—and achieve the financial freedom I’d been seeking for so long. I created “Aprender sobre Finanças” to share what I’ve learned through hands-on experience—no fluff and no unrealistic promises. Here you’ll find real content from someone who actually invests.
