Frequently asked questions
Can you build a custom Shopify app?
Yes. I build both public Shopify App Store apps and custom (private) apps using Remix, React, Node.js, Polaris, and App Bridge, backed by the Admin GraphQL API and webhooks. This includes OAuth flows, App Store submission, and store-specific automations, dashboards, and integrations that off-the-shelf apps cannot handle.
Do you work with Shopify Plus and Checkout Extensibility?
Yes. I develop on Shopify Plus, including Checkout Extensibility, checkout UI extensions, and Shopify Functions to replace legacy Scripts. I handle custom checkout logic, discounts, and validation for high-volume stores.
Can you migrate my store to Shopify from another platform?
Yes. I migrate stores to Shopify and Shopify Plus from Magento, Salesforce Commerce, WooCommerce, BigCommerce, and custom legacy stacks, including data, URLs and redirects, theme rebuild, and re-integrating apps and APIs so you do not lose SEO or functionality.
Do you fix bugs in existing Shopify apps or themes?
Yes. I debug and fix existing Shopify apps and themes, including broken checkout flows, failing webhooks, API rate-limit issues, Liquid errors, and JavaScript bugs. I can work from your existing codebase and ship a fix without a full rebuild.
Can you integrate Shopify with an ERP, CRM, or third-party API?
Yes. I connect Shopify to ERPs, CRMs, inventory and logistics systems, payment gateways, marketing tools, and custom backends using the Admin GraphQL & REST APIs, Storefront API, and webhooks, with reliable retry and error handling.
Can you build a headless Shopify storefront with Hydrogen or Next.js?
Yes. I build headless and composable commerce storefronts with the Storefront API using Hydrogen and Oxygen or Next.js / React, tuned for Core Web Vitals, SEO, and fast data fetching.
Do you do ongoing Shopify store management and support?
Yes. Beyond development I can handle day-to-day store work: product and collection setup, content updates, QA before launches, third-party app management, and troubleshooting, on a retainer or as-needed basis.
How much does a custom Shopify app or theme cost?
It depends on scope. Small bug fixes and integrations are billed hourly or as a fixed quote, while larger custom apps, migrations, and themes are scoped as fixed-price projects. Email me with what you need and I will send an estimate.
Do you work with agencies and on a contract or freelance basis?
Yes. I work fully remote with merchants and agencies worldwide on freelance, contract, and white-label projects, in English and Turkish, and adapt to your timezone for key calls.
