Serbia-based full-stack developer specializing in Shopify Hydrogen storefronts, headless commerce architecture, and CRO. Upwork Expert-Vetted Top 1%. I build custom headless storefronts (Hydrogen + React Router), extend and integrate Python/Django backends, and wire up the entire stack — Algolia search, Storyblok CMS, GraphQL (Shopify Admin & Storefront), ERP/PIM/CRM integrations, and CI/CD pipelines for Shopify Oxygen and edge deployments. I also specialize in Shopify Plus theme development, CRO, migrations (Liquid → Hydrogen, WooCommerce → Shopify, Django-based frontends → headless), and the third-party integrations (Klaviyo, Checkout Champ, ShipperHQ, Replo, and more) that make a store actually run. Check my portfolio at stargazerstudio.net/portfolio I mainly work with UK/US brands, often picking up projects where a previous developer stalled or disappeared mid-build — including complex headless setups where standard Shopify assumptions don't apply. In today's global economy, my goal is to give you senior-level, agency-quality work at a fraction of agency overhead. Over 10 years of experience working with brands and agencies. Shoot me a message and I'll give you a quote! My work blends engineering, CRO principles, and product thinking — focused on reliability, performance, and revenue impact. I'm also AI-fluent: comfortable using AI-assisted workflows to move faster without cutting corners on code quality. Before specializing in Shopify and full-stack ecommerce, I also worked in 3D (Cinema 4D, Octane Render) and shipped projects for major brands — that background gives me an edge on design-heavy, cross-functional builds.
