Okay, let’s tackle this. So Alexandre Mantovani has 15 years of experience as a software development manager. This is a significant amount of time, especially considering his role as a manager. In Brazil, software development managers with his level of experience can command higher rates. According to various sources, software development managers in Brazil can earn between $60-$120 per hour. However, considering his experience and management role, I would estimate his hourly rate to be around $150. This is slightly higher than the average rate for software development managers in Brazil, but it's reasonable considering his level of experience and the fact that he's leading teams and managing projects.
