I design and build Shopify apps end to end - Admin API integration, OAuth, webhooks, recurring billing and the embedded admin UI merchants actually use. Apps I've built: Amazon Product Importer - lets merchants pull Amazon listings into their Shopify store in one click. Handles title, description, images, variants and pricing, with scheduled re-sync so prices and stock stay current. Built on the Shopify Admin API with a resilient scraping layer (proxy rotation, retry and rate-limit handling) so imports don't break when the source page changes. eBay Product Importer - the same workflow for eBay listings, including variant mapping and bulk import for sellers migrating an entire catalogue. Affiliate Buy Button - adds a configurable "Buy on Amazon" / "Buy on eBay" button to Shopify product pages, so merchants can route buyers to their marketplace listings without editing theme code. Fully theme-aware and configurable from the app admin. Beyond Shopify I build backend and automation software in C#, Python and PHP: REST API integrations, web scraping pipelines, Selenium automation and Telegram bots for order and inventory alerts.
