About SyntaxRepairs

We specialise in **Shopify app development** using modern stacks (Remix + Polaris), with a focus on performance, maintainability, and clean admin experiences. Our approach is pragmatic: ship what merchants need, keep it fast, and make it easy to iterate.

Coming soon: more lightweight utilities for marketing teams, theme tooling, and automation. This page will grow with links to each app, docs, and policies.
