Shopify Developer

Summary: Breathe.'s website runs on Shopify and is mid-way through an incomplete rebrand (from CellRegen). We're looking for a Shopify developer to finish the technical side of the rebrand, build new conversion-focused pages, improve the booking experience, and make sure the site connects cleanly to Timely (booking) and Mailchimp (email).
Responsibilities:

Finish the rebrand at the technical level: title tags, meta descriptions, og:images, any labels/assets still carrying the CellRegen name; set up a 301 redirect from ---------- to ----------
Build new pages/sections in the theme: "Why Breathe / Our Technology" (price justification), a social-proof section (reviews + client stories), a wellness-tourism landing page, and a B2B/corporate landing page
Reorganise how services are presented and streamline the booking path to reduce friction; clean up the service menu with its overlapping/duplicate names
Improve how Timely is integrated and presented on the site (embed, booking buttons, GMB?booking pathway)
Set up and validate the Shopify ? Mailchimp integration (official app) and support the connection to Timely
Implement GA4 and Meta Pixel
Build from the supplied design mockups and copy

Must have:

Shopify theme development (Liquid, HTML/CSS, JS)
Experience with Shopify integrations/apps (Mailchimp; ideally familiarity with booking embeds such as Timely)

Nice to have (a real plus, not required):

Technical SEO (redirects, metadata, structured data, on-page structure)
A good eye for faithfully implementing a premium brand design
CRO awareness
