Build a High-Converting Landing Page for Lead Generation (Shopify or WordPress)

I'm looking for an experienced developer to build a conversion-focused landing page designed to generate qualified leads. This is not a basic landing page. The focus is on speed, user experience, conversion rate, tracking, and marketing integrations...
