Hello!
I have a functional understanding of Chef and its underlying environment. All the work I've ever done is on Vagrant, with using chef_solo and Berkshelf for my own local development. I don't have a lot of experience with ChefSpec, but I do verify my work with Kitchen and Rubocop before before pushing the recipes to a production chef server.
I completely understand if you want to go with someone more experienced in this field, but thank you in advance for your consideration.
Cheers,
Nick
