I have been an engineer and software developer for over 45 years.
I typically do not develop software as an end product, some Android apps (like BusinessLog) being the exception. Most of my software work is in support of the products I develop and build.
Also I do not develop only for prototypes, I typically work on requirements where at least dozens of boards are required, up to several thousands.
If you need a board to control something, remotely via radio or not, controlled through an app or not, talk to me (email link at the bottom of any page)
