I was an employee from January to March, and then started to be a subcontractor for the rest of the year for the same person. Is this ok?

Is it ok to file a W2 and 1099 from the same person?

Yes, this is not an issue. Just remember to track your expenses accurately now that you are "self-employed". You are subject to self-employment tax once you are a subcontractor and you want to capture all expenses to keep your taxes as low as possible.
