"5 stars is not enough. Sasha literally looked at my code for the 1st time, diagnosed, and corrected the issue in under 5 min including explaining it to me... on a problem I had been struggling on for 40 hours+. And I had another code mentor session with someone else for over 2 hours that couldn't solve it. Additionally, he took time to explain why I wasn't using best practice and without even refactoring was able to make the code more 100x easier. He solved my issue so quickly, that I spent the next 20 min discussing theory and best practices with him and have shifted my approach to all future development."
