Just like 'There is no such person as Good CEO', but only 'A Good CEO for a particular company, at a particular point of time', there is no such a person as 'Good Programmer', there is only 'A Good Programmer for a particular job, at a particular point of time'.

Context matters a lot. One does not use an AK-47 to kill a mosquito. It is terrible for that job. But that does not make AK-47 a terrible weapon.

Good at programming competitions does not equal good at any programming job, is a more appropriate sentence.
