Starting a sentence with the word 'After'

[Unregistered]

Can I start a sentence with the word 'After'? I cant find a list of words not to use at the begining of a sentence and im not sure if after sounds correct.

e.g. After graduating from university with a first class honours degree in 2004, I began my career managing scientific research projects.

That is totally fine.

You are not supposed to start a sentence with and, but, or, nor in formal writing.
