Frequently asked questions
Can you build a custom Shopify app?
Yes. I build both public App Store apps and custom private apps with Remix, React, Node.js, Polaris, and App Bridge, backed by the Admin GraphQL API and webhooks. This covers OAuth, billing, App Store submission, and the store-specific automations, dashboards, and integrations that no off-the-shelf app handles.
Have you published apps on the Shopify App Store?
Yes. I have built and published my own Shopify apps, including BlogPilot AI, AgentRank, and Stockcast, so I know the full path from idea to a live, reviewed App Store listing, not just the code.
What is the difference between a public and a custom app?
A public app is listed on the Shopify App Store and any merchant can install it, with OAuth and billing. A custom (private) app is built for one store's specific workflow and is not listed. I build both, and help you choose which fits your goal.
