Ich erstelle eine maßgeschneiderte Software nach deinen Bedürfnissen

I'm a back-end software developer used to work in full-stack. My main code language is C#, followed by PHP, but it's not strange for me to use languages witch i have little or no use. To make user interfaces i mainly use WinForm or various type of HTML/ASP .NET variants, CSS included of course. For data managment i use mainly NoSQL(A.K.A. files managed by the software itself) or SQL(mainly MS SQL or MySQL). I'm a perfectionist and i tend to overtest my softwares until i think it's perfect. All my softwares have backup protocols to make easy to give me the rare errors that i didn't see.
