We're using VWO (A/B testing tool) to create variations of pages on our website. Some of these variations require adding custom js, css and html to our existing pages. We're looking for an experienced Front End developer to write small custom js scripts and custom css that would help create the variations on our pages in our editor. Anticipated workload: ~ 1-2 hours per day of coding. Criteria for acceptance: variations resulting from adding custom code to VWO's editor will display according to design and consistently across browsers.
