Hi, my name is
Komal Raza
Full-Stack Engineer & Shopify App Developer
Building scalable Shopify apps and SaaS products with React, Node.js, and PostgreSQL. Turning complex business requirements into clean, production-ready software.
About Me
I'm a Full-Stack Engineer with over 2.5 years of experience building production-grade Shopify apps, SaaS platforms, and e-commerce solutions. I specialize in architecting systems that solve real business problems for merchants and product teams.
My core work revolves around custom and public Shopify app development, subscription billing systems, analytics dashboards, and API integrations. I focus on writing clean, maintainable code that scales with business growth.
I've worked across the full stack — from building responsive UIs with React and Tailwind CSS to designing RESTful APIs with Node.js and managing PostgreSQL databases. I care deeply about developer experience, code quality, and shipping features that matter.
