Wordpress Full Stack Developer

We need an experienced Wordpress developer who has an eye for design as well as a deep understanding of PHP/MySQL. You must be able to convert a PSD to HTML/CSS+SCSS, work with Grunt + GIT and build database-heavy plugins.

Tasks will include:

- Optimizing code for # database calls and speed
- Create new templates from PSD's and altering existing SCSS codebase
- A/B testing changes to the site
- Etc.

Please reply with answers to the following:

1) Describe one complex piece of code you had to write for Wordpress that you are most proud of.

2) If our website was slow and had no caching, what type(s) of caching / plugins would you use to speed it up?

3) What is the css class for buttons in Bootstrap?

4) What is your favorite part about web development?

Thanks!
