User Experience Designer

Desperate plea for survey participants!

Hello and happy Friday! I am a handful of responses away from being able to conduct analysis on my doctoral research around UX and Learning design professionals and their perceptions on software learnability! Please consider taking 10-15 mins out of your day to help a grad student out and complete my survey!  https://odu.co1.qualtrics.com/jfe/form/SV_d12h5XO1NnuQowm 

I'm not too proud to beg, and any additional leads or recommendations on where I might be able to get more respondents would be much appreciated! my email address is cmill045@odu.edu if you have any questions or leads!

Can anyone help me with this? Much appreciated.

I have been trying to deploy apex classes to a Trailhead Playgound as well as a developer org, but I receive the error "SFDX: Deploy Source to Org failed to run" in VS Code.

Component conversion failed: This directory does not contain a valid Salesforce DX project.

Hello
I'm interested in learning about User Experience Designer. Is anyone here already certified and what teaching method did they use?
