I am looking for an experienced Shopify developer or agency to migrate my existing WooCommerce website to Shopify. The site has around 3,000 products with technical specifications and uses a live supplier API feed that updates product data, pricing, stock and images daily, so this migration must include a fully functional automated feed solution. I require complete migration of all products, categories, images, SEO metadata, blog posts and (optional) customers, along with 301 redirects to preserve rankings. The new Shopify build should use a high-performance theme such as Impulse or Warehouse with a custom mega menu, fast mobile-friendly layout, and a professionally styled design. Product pages must use Shopify metafields to automatically populate specification tables, including dimensions, temperature range, voltage, refrigerant, cooling type, capacity, power, weight, energy label, warranty, brand and PDF spec sheets. The developer must handle live API integration using Stock Sync, Matrixify or a custom script, ensuring daily syncing and correct handling of discontinued products. Additional requirements include quote request functionality, finance/payment options, freight-based shipping rules, merchant centre compatibility, JSON-LD SEO setup, and correct canonical and sitemap configuration. Only developers with proven experience in large catalogue Shopify builds, WooCommerce migrations, and API integration should apply. Proposals must include total cost, timeline, tools/apps to be used, examples of similar work, explanation of how the API syncing will function, and confirmation of post-launch support
