Web Designer + Coder + Jquery + Social Media Images

We are looking for someone to join our team who will do the following:

- Help the social media team to produce images for campaigns/posts
- Help to tweak designs or do fully new designs
- Do Jquery/javascript coding for front ends
- Create web designs or edit existing designs to look better
- Take those designs and code them into HTML / CSS

Please let me know which of the above you can do and any learning you'd need. Ideally provide an example for each of these items so I see 1) you understand the job post 2) you can do the job!
