Another excellent session with Errietta, she helped me with some tricky UI router logic for the sub Navigation that I was working on. One of my Sub Navigation menus were not working and she helped me resolve the issue and was kind enough to explain it to me. She is very knowledgeable and a very good code mentor. I will definitely seek her assistance again if I need help.

Another informative session with Errietta, she helped me debugg some AngularJS logic that I was unsure of and she also helped with custom styling of a popover. She is very informative and a very good, knowledgeable mentor.
