I started testing, there I was able to learn about tools such as: Postman, Jmeter, SOAP and Selenium (with .NET). After the first month and a half I started developing, with .NET Core and .Net Framework, I learned the Repository and CQRS design patterns; Additionally I apply unit tests using XUnit, to make sure that I am delivering quality code. Finally, since December of the previous year I have been working with Angular.
