Website for Hardware and Software Platform

We have launched a website (peakVO2fit.com) via squarespace for a portable hardware device and software platform. Because we have three options of subscription, Squarespace payments are insufficient, and we need to process transactions directly via Stripe. We are looking for an experienced developer to build this integration, optimize our SEO, and configure our pre-order workflows. ​Scope of Work ​Stripe Integration: Build a direct Stripe checkout flow that seamlessly supports our three subscription tiers. ​Pre-Orders & Referrals: Implement a waitlist funnel that captures pre-orders and generates unique referral codes for early adopters. ​SEO & Tech Tasks: Audit and implement technical and on-page SEO, and integrate dynamic QR codes linking physical assets to digital flows. ​Required Experience ​Advanced Squarespace development and Stripe API integration. ​Proven track record with technical SEO, referral systems, and pre-order workflows. ​Bonus Skills ​Sales Funnels & Email Outreach: Experience designing high-converting sales funnels and automated email campaigns for B2B or hardware launches. ​To Apply Please share examples of custom Stripe integrations you have built. Briefly explain your approach to generating referral codes for pre-orders, and mention your preferred email or funnel platforms.
