WooCommerce Backend Customization - HTML/Tailwind

WooCommerce Backend Specialist (Tailwind HTML + Square + Product Matrix) Job Title: WooCommerce Specialist: Integrate Static Tailwind HTML + Product Add-ons Matrix Project Overview: We are a premium Direct-to-Consumer (D2C) architectural blinds company. Our frontend visual shell is 100% finished, tested, and built in pure, lightweight HTML5 and Tailwind CSS (via CDN) with Vanilla JS. WE DO NOT NEED DESIGN WORK. WE DO NOT NEED REACT. WE DO NOT WANT PAGE BUILDERS. We need a surgical WordPress/WooCommerce developer to take our static .html files, convert them into a lightweight custom theme, and map our predefined pricing logic to the WooCommerce checkout flow. Scope of Work: Theme Conversion: Chop our provided HTML files (Homepage, Indoor Product, Outdoor Product, Consultation) into a clean, custom WordPress theme (header.php, footer.php, front-page.php, single-product.php). Your job is to wrap standard WooCommerce outputs in our existing Tailwind CSS classes . WooCommerce Setup: Install and configure core WooCommerce. Ensure the Cart and Checkout pages adopt our brand styling (Gunmetal Slate #2C3539 / Tybee Sand #D9D4C5) . Parametric Pricing Matrix: Our products use dimension-based pricing (Width x Drop) along with predefined modifiers (e.g., +150forstandardmotors,+280 for smart motors). You will install a plugin like WooCommerce Product Add-ons or Uni CPO to input our exact pricing matrix so the user can configure and buy dynamically . Payment Integration: Connect and configure the official Square payment gateway for seamless, invisible checkout processing . Hard Constraints: Tech Stack: PHP, WordPress, WooCommerce, Tailwind CSS, Vanilla JS. NO page builders (Elementor, Divi, WP Bakery). You must hardcode the templates to protect our layout and load speeds . To Apply, You MUST Answer: Have you built custom WooCommerce themes directly from static HTML/Tailwind before? Provide one specific example. Which plugin do you prefer for complex product variations/pricing matrices (e.g., WooCommerce Product Add-ons, Uni CPO, etc.) and why? Confirm you have integrated the Square payment gateway with WooCommerce before. Confirm you understand this is a project with no frontend design work required.
