Difference in Difference in Stata 17 -- 2

I am conducting a research project using the Difference in Difference (DiD) method. Due to the complexity of this approach and my limited experience, I am unsure if I require any additional Stata packages. But I do know that I need to do this research project using Stata version 17. I am looking for a freelancer who is familiar and experienced with both DiD as well as Stata 17, and who can help me get the best possible results in the least amount of time.
