"I had a very helpful session with Errietta, she helped me with some UI router logic for displaying some Sub Navigation menus that I was working on. Errietta is always helpful and very knowledgeable."

"Errietta is up for all sorts of challenges. I haven't yet had a session with her where she shrinked away or had to get back to me later. She is a wealth of knowledge and I highly recommend hiring her!"

Todd Squitieri

"Errietta helped me with HTML and css-styling and also helped me modify a jQuery plugin for a website that I was making for my friend. I LOVED how Errietta allowed me to do all of the work, as slow as I was. So many code mentors want to take control of the mouse and do all of the work for you. I think this makes it more difficult for a person to learn. Errietta clearly has been teaching for a long time and knows how important it is for students to do the work themselves. Definitely sign up for this mentor if you genuinely want to learn new skills!"

"Another informative session with Errietta, I had two problems that I needed help with and she helped me with one of the problems and put me on the right path with the other problem. I will definitely seek her assistance again because she is very knowledgeable."

James

"First off, this was a monster of a problem and it wasn't easy and it wasn't an easy fix. Errietta was patient and took some time understanding how the app is set up and how files were related to each other. At the end she solved the issue and was able to explain the issue and solution in the simplest of terms to me. I highly recommend her and will definitely be calling on her again."

"Errietta is amazing. She never backs down from a challenge and is always pleasant. She's always got a clever solution even if I have to impose some strict restrictions - vanilla JS only being one of them. I cannot express how grateful I am to have found her. Please do pair with her, you won't regret it!"

"This was my first session with Errietta, she was very knowledgeable in helping me with my questions on using ui router's StateParam as well as some styling issues I was having. I will definitely seek her help again."
