Shopify App Developer

Copyfy is the #1 product intelligence tool for French-speaking e-commerce operators. We're currently at $150K MRR and aiming for $300K MRR by end of 2026. Our next big move? Launching the AI Store : an AI-powered Shopify store generator that lets our users spin up a fully optimized store in minutes, without writing a single line of code. This is an ambitious, technically challenging product that will reshape how thousands of dropshippers launch their business.

• —Knows the full ecosystem: Admin API, Storefront API, GraphQL, Webhooks, App Bridge, Polaris
• —Is comfortable with OAuth, Billing API, and the realities of the Shopify App Store review process
• —Cares deeply about performance and UX (Core Web Vitals, theme inspector, etc.)

Your mission

• —Build the Shopify store generation engine (theme creation + programmatic customization)
• —Develop a public Shopify app connected to Copyfy
• —Architect OAuth flows, install/uninstall logic, billing
• —Work closely with our product/AI team to integrate GPT/Claude into the generator
• —Ship fast, write clean and scalable code, ready to serve thousands of users

Logistics

• —Freelance contract, starting ASAP
• —4 to 5 days/week for ~3-6 months minimum
• —Long-term partnership possible if it's a great fit
