If all Experts really were experts and all Professionals really were professional then I would be likely be out of a job.
I am that quiet weird guy who sits in the corner who everyone avoids until something goes wrong at which point I transform into that guy that can sort out any problem on any system 'like magic!', even after the 'experts' said it wasn't possible.
In reality I am just a data analyst with a natural understanding of the core concepts behind most modern systems and language structures who isn't ashamed to google to fill gaps in my knowledge whenever necessary
