I am working on my 'Statement of Purpose' for my grad school application. It seems that correct punctuation is very critical. So I have a question about the comma punctuation in the following sentence
Since the time I have come across the powerful and intelligent tools like face and speech recognition, machine translation[,] I have been fascinated about exploring the field of 'Artificial intelligence' and 'Algorithm design'.
Is the comma in  after 'machine translation' correct? What I want is that, I want the comma to end the previous series of examples and add a new independent phrase, but I feel like there is a possible interpretation of understanding the phrase 'I have been fascinated about ..' as another example of the ongoing series, i.e., interpreting it as tool rather than independent clause.
What is the correct comma use here?
