Building document classifier based on keywords, what would be the steps?

Question

I have a requirement of classifying documents(.doc files) based on the profiles. I have a csv file with data:

label          keyWords
Web developer  ["html","css","php"]
Developer      ["core","java","python"]
Embedded Dev   ["ARM", "CORTEX", "C"]

Now I want to classify the .doc files.

Also please do tell me what model to use ? or broad steps for proceeding (like building dataframe-> then splitting data and so on...)

EDIT:
Any pointers on how to proceed with document classifier ?
