    Jin has been great to work with, very kind, very pleasant, and definitely technically skilled. Being a software engineer myself, I came in with very clear requirements for a FireFox extension by providing a BDD Gherkin file which Jin just ran with, I didn't ask him any questions and he didn't ask me many questions either, the work was done efficiently and quickly. A+++ I will be working with Jin in the future!
