I think you mean "Q & A" and QA. QA = "Quality Assurance".

Thank you for pointing out! I just changed the article's "QA" to "Q&A". Now, the title is:

Building a Q&A web service in an hour - MEAN stack development(3) http://engineering.paiza.io/entry/2016/03/10/115345

I think you mean "and not QA" and not "and QA". :) But I agree, it should be "Q & A".
