The word "professional" is overloaded. Perhaps a better term is "government certified professional". Medical doctors and (physical) engineers must meet a prescribed set of minimum standards and take an oath. Attempts to form a set of software standards to be used in a similar way has proven elusive. Software is too malleable, and languages and "state of the art" architectures come and go like clothing styles (often without merit in my opinion). Physics and the human body don't change very often. Software approaches do.
