Hamza was a true partner throughout this process. He provided valuable insight for the best deployment structure at my stage and worked with my other team members very well. He was always incredibly responsive and professional. Great work and I know I will be working with him in the future.

I’m not just a developer working on demo projects — I’ve built and run production ecommerce systems handling real customers, payments, shipping logic, and performance optimization. I understand what makes Shopify stores not only function properly, but convert visitors into customers.
I can help you with:
• Complete Shopify store setup from scratch
• Custom theme design and Theme 2.0 customization
• Conversion-optimized product pages and layouts
• Speed optimization and performance improvements
• Payment gateway, shipping, and tax configuration
• App integrations and custom functionality
• Mobile optimization and responsive design
• Store fixes, improvements, and ongoing support
I focus on building Shopify stores that are:
• Fast and responsive
• Clean and professional
• Easy to manage
• Built for long-term scalability
Technical expertise:
• Shopify (Theme 2.0, Liquid, APIs)
• Custom theme development and customization
• JavaScript, React, Next.js
• Performance optimization and Core Web Vitals
• API integrations and backend systems
If you're looking for a Shopify developer who understands both the technical side and the business side of ecommerce, I can help you build a reliable, high-quality store.
Steps for completing your project
After purchasing the project, send requirements so Hamza can start the project.
Delivery time starts when Hamza receives requirements from you.
Hamza works on your project following the steps below.
Revisions may occur after the delivery date.
Requirement gathering
Understand Client Needs: Define the purpose and expected outcome of the integration. Identify the systems to be integrated (CRM, ERP, payment gateway, etc.). Check for security, compliance, and performance requirements.
API Design & Architecture
Choosing the Right Approach: REST, SOAP, GraphQL, or Webhooks? Decide if synchronous or asynchronous communication is needed. Define how data moves between systems. Map required transformations (e.g., currency conversions, time zone adjustments).
