Which one is correct to describe that I started something and it's still continuing since then.
I've started doing the project
Or
I started doing the project
I don't know the first one sounds like I've started it several times, or I am still starting it, since the present perfect is to the "start" not what I've actually been doing, however I mean to say that I started it in the past but the actual activity is still going since then, and the second sentence can be even worse that I started doing it in the past but not anymore, which one is correct?
Please stick with the both phrases, I understand that there are better ways to phrase the sentence, but regardless.

Both of those are correct. The past participle expresses a completed action. Since the act of starting to work on the project is already done, it is correct and can be used in your case. However, in this particular case, when you use the past tense, you won't sound natural if you don't provide a timeframe, since the sentence sounds incomplete. Also, you don't "do" a project, you "work on" it.
