I build custom Shopify apps and WordPress plugins for merchants who need something specific that no existing solution covers. My work ships to production: apps approved on the Shopify App Store and plugins published on the WooCommerce Store.
5+ years building ecommerce software for clients across the US, UK, and MENA. I work on complex backend logic, API integrations, custom checkout, pricing systems, and admin dashboards using React, Node.js, PHP, and Laravel.
If you have a real problem that needs a real custom solution, send me the details and I will reply with a clear plan and timeline.

FAQ
Do you build both Custom (Private) and Public Shopify Apps?
Yes! I build Private/Custom Shopify apps for individual stores as well as Public Apps designed for the Shopify App Store. This includes OAuth, billing setup, Polaris UI, and app store compliance.
What technologies do you use to build Shopify apps?
I use Node.js, React, Shopify Admin API (REST + GraphQL), Storefront API, Polaris UI, MongoDB, and sometimes Laravel/MySQL depending on the project.
Can you integrate external APIs such as ERP, CRM, or WMS?
Absolutely. I regularly work with ERP, CRM, shipping APIs, accounting systems, inventory platforms, and other third-party services. I can also build full sync apps with cronjobs, queues, and caching.
Can you build an app that works on multiple Shopify stores (multi-tenant)?
Yes, I can build multi-store or multi-merchant apps with OAuth authentication and scalable architecture, ideal for launching a SaaS product.
Do you help with Shopify App Store submission and approval?
Yes. I follow Shopify’s app review guidelines and can prepare your app for submission, fix rejections, and ensure compliance.
Will the app affect my existing theme or store performance?
No. My apps are optimized for performance and follow Shopify-approved development patterns so your storefront remains fast and secure.
Can you build automations like tagging products, syncing inventory, or generating reports?
Yes! I can build advanced automation tools, custom workflows, scheduling, and admin-side utilities to save you time.
Do you provide documentation and support?
Yes. Every app includes documentation, code structure explanation, and post-delivery support. Premium package includes extended support.
Can you redesign my theme or create a Shopify website?
This gig focuses on Shopify app development, but I can also help with theme edits, custom features, or recommend a dedicated gig for full store development.
What do you need from me to get started?
I usually need: • Store URL • App type (Custom or Public) • Features required • Any reference apps • API documentation (if external integration needed)
