FAQ
Frequently Asked Questions
Can you build APIs for US systems?
Yes. I work remotely and can build APIs for US companies with clear scope, access, milestones, and handover.
Can you integrate Shopify with ERP or CRM systems?
Yes. Shopify API and ERP sync work is a strong fit, especially when the business logic needs to sit outside the theme.
Can you work with existing Node.js, PHP, or WordPress code?
Yes. I can review existing code before committing to a fix or takeover.
Can you take over a half-built API?
Usually, yes. The first step is a review of the codebase, environment, logs, dependencies, and current failure points.
Need systems connected?
Send the systems, the source of truth, current errors, and the business outcome.
