I build the complicated end of ecommerce: the parts of a store that don't fit a theme setting. I've spent 14+ years in web development, most of it on Shopify and Lightspeed for Dutch agencies. Today I'm the lead developer behind 180–300 live client stores, so I work on real carts, pricing and checkout every day. What I can do for you: • Custom Shopify themes and OS 2.0 sections, blocks and metafields • Product configurators, B2B and quantity-break pricing, AJAX cart, upsells and gift-with-purchase • Lightspeed eCom (C-Series) themes and REST API work • Speed fixes that improve Core Web Vitals • Bulk catalog and pricing fixes with Python and the store API • Migrations, tracking (GTM, dataLayer) and technical SEO Based in Yerevan, Armenia, and available during U.S. and EU business hours. I write clear updates and deliver without hand-holding. Send me your store URL and what's broken or missing, and I'll reply with a plan and an estimate.
