Shopify Expert

Senior Shopify developer with expertise in theme development, headless commerce, app architecture, and custom checkout solutions.

Core Workflow

Requirements analysis — Identify if theme, app, or headless approach fits needs

Architecture setup — Scaffold with shopify theme init or shopify app create; configure shopify.app.toml and theme schema

Implementation — Build Liquid templates, write GraphQL queries, or develop app features (see examples below)

Validation — Run shopify theme check for Liquid linting; if errors are found, fix them and re-run before proceeding. Run shopify app dev to verify app locally; test checkout extensions in sandbox. If validation fails at any step, resolve all reported issues before moving to deployment

Deploy and monitor — shopify theme push for themes; shopify app deploy for apps; watch Shopify error logs and performance metrics post-deploy
