A/B Testing for Shopify stores

I'm looking for an experienced A/B tester to build tests for Shopify eCommerce stores.

Requirements:
- Create A/B tests from scratch based on provided Loom video and Figma file
- Set up tests in Intelligems (experience preferred but not mandatory)
- Range of tasks from simple text edits to complex page rebuilds

Ideal skills:
- A/B testing expertise
- Shopify experience
- Familiarity with Intelligems is a plus

Initially, this is a per-project basis, with potential for long-term hire.
