i am professional who have been dedicated to the system's world for years. i am always looking for technological innovation in our projects, in order to offer the client the best option, according to their needs and possibilities.
i have extensive experience in backends developed with C #, mainly using .Net Core and Entity Framework, with SQL Server databases. I also know about full frameworks (versions 1.1, 2.0, 3.5, 4.0, 4.5) that preceded .Net Core and our experience with databases is not limited to just SQL Server, we have also used MySQL and MongoDB.
Additionally, i have experience in frontend, using Angular from its first versions (AngularJS) to the most recent ones, going through the intermediate versions. But we don't just limit ourselves to Angular, we also know about React, MVC and Blazor. Our experience also involves mobile apps, developed with Xamarin and others with React Native.
Finally, my experience also includes integrations between systems, using REST and SOAP services. I have worked for years also with equipment that uses RFID and other types of input/output sensors.
