Track record
Capabilities
5+ years building on Shopify — Liquid theme development, Online Store 2.0, Checkout Extensibility, metafields and metaobjects, and Shopify Plus. Comfortable across the full theme stack — from section and block JSON schema to metafield-driven dynamic content.
Fluent in the Shopify Admin GraphQL API — the backbone of the internal dashboards and product-data exports built for the team. Builds and maintains a Zapier pipeline syncing custom storefronts to a Pipedrive CRM, and manages marketing and analytics tracking (Meta, TikTok, Northbeam, AppLovin) end to end. Familiar with ERP order and inventory sync (Fulfil.io), monitoring data flow to prevent outages and unexpected behavior.
Actively working with the Shopify AI Toolkit and Dev MCP — using AI coding agents (Cursor, Claude Code) to generate schema-validated GraphQL queries, introspect live APIs, and accelerate storefront development without hallucinating deprecated endpoints.
Proficient in HTML5, CSS3/SCSS, JavaScript (ES6+), and Tailwind CSS. Delivers pixel-perfect, maintainable UIs across complex Shopify themes. Works with Lighthouse and LCP metrics to identify and fix performance bottlenecks — including lazy-loading strategies for video-heavy pages.
Owns end-to-end Git workflows in multi-developer environments — branching strategy, conflict resolution across freelancer and production themes, and deployment pipelines. Experienced onboarding developers and training non-technical teammates on custom tooling.
Uses AI tooling (Cursor, IntelliJ AI, Figma MCP, Claude Code) as a force multiplier — not a replacement for judgment. Accelerates iteration cycles, generates boilerplate, and reviews AI output critically before committing to production.
