I completed my project at all 🙅🏼♀️ No. We can only use AT ALL in negative sentences. For example:
I did NOT work on my project AT ALL.
I don’t want to talk to her at all.
I won’t see him at all.
In positive sentences, we can use totally, completely, or the whole (thing):
I totally completely my project.
I completely finished my project.
I completed the whole project.
