MF Rural - The biggest brazilian rural e-commerce It started in early 2005, I was just 18 and I already was deeply immersed in IT work and rural fields. At that time, I had already launched some professional websites to Canal do Boi (a rural national TV channel) and to some auction companies in Brazil. So I received a visit from some guys from another state (São Paulo), who wanted to create a new way to make business in the rural field. ...
I recently published a detailed technical article on Balta.io-one of the premier .NET ecosystem references in Brazil-addressing a critical topic for high-performance systems: concurrency control. As software engineers with extensive experience in high-demand solutions, we often face the challenge of “doing as much as possible, as fast as possible”. However, infrastructure realities-such as rate limits in third-party APIs or hardware constraints-force us to understand exactly when and how to throttle our execution. ...
Dependency Inversion (D) in SOLID: Why Is It So Important? The Dependency Inversion Principle (D) reminds us that “high-level modules should not depend on low-level modules; both should depend on abstractions.” This means clients (code consuming functionalities) should rely on interfaces or abstractions, not concrete implementations. This practice reduces coupling, simplifies changes, and makes code more testable. For example, instead of directly coupling a notification service to a concrete class like EmailSender, use an interface such as IEmailSender. This allows you to easily swap implementations (e.g., SMTPClient, API service, message queue, etc) without modifying the client. ...
