FAQ
Do you build custom Shopify themes, or do you use pre-made templates?
I specialize in building fully custom Shopify themes from scratch using Liquid and Tailwind CSS, as well as heavily modifying premium themes. For enterprise clients looking for maximum performance, I also design and build decoupled, headless commerce architectures using Shopify Hydrogen and Next.js.
Can you migrate my existing store from another platform to Shopify?
Yes. I handle complex end-to-end data migrations from platforms like WordPress/WooCommerce, BigCommerce, and Magento. This includes securely migrating your entire product catalog, customer databases, order histories, and SEO configurations without losing organic search rankings.
Will my store be fully optimized for speed and mobile responsiveness?
Absolutely. Every storefront I develop features a mobile-first responsive design. I optimize core web vitals, implement lazy loading, minimize code bloat, and streamline app scripts to ensure fast loading times and optimal conversion rates.
Can you connect Shopify to third-party ERPs, CRMs, or custom APIs?
Yes. I have extensive experience building custom integrations via Shopify's REST and GraphQL APIs. Whether you need to sync inventory with an ERP, connect to a custom fulfillment center, or set up automated third-party payment gateways like Stripe for subscriptions, I can build a secure solution.
What do I need to provide before we start development?
You will need to provide your Shopify store access (or I can set up a development store), your branding assets (logo, fonts, color palettes), product copy/images, and a clear list of required pages or features. If you have wireframes or Figma designs, please share them during our initial discovery m
