Senior Shopify Developer specializing in headless commerce, custom themes, and performance-first storefronts.
What I'm looking for
I’m a Senior Shopify Developer with 5+ years of hands-on experience building, customizing, and optimizing Shopify and Shopify Plus stores for small businesses and fast-growing eCommerce brands. I take end-to-end ownership to deliver scalable, conversion-focused storefronts.
My work centers on custom theme development and advanced Shopify functionality, including Shopify Plus theme infrastructure, Liquid design patterns, and custom Metaobjects. I also architect headless storefront experiences with React, Next.js, and the Shopify Storefront API to decouple services and improve initial load velocity.
I’m careful about extensibility and reliability—implementing secure Shopify Functions and Checkout Extensibility to deploy discount logic and tailored checkout validations without breaking upgrade paths. I’ve also built custom private apps using App Bridge and Node.js to synchronize enterprise inventory across third-party fulfillment endpoints.
I continuously raise quality through performance optimization and automation, using Lighthouse core web vitals, Webpack Bundle Analyzer, and CI/CD with GitHub Actions. I collaborate in Agile teams (Jira/Confluence) to refactor legacy code, introduce TypeScript, and ensure stable releases—while integrating services like Stripe, PayPal, Klaviyo, Yotpo, and Algolia.
