I'm a Senior Shopify Developer and full-stack engineer working with e-commerce brands and agencies internationally. My core lane is Shopify Plus — custom Liquid, Online Store 2.0 section architecture, metafields, migrations, and the performance work that keeps Core Web Vitals green. Underneath the storefront I build in Python: REST integrations, back-office automation, and production AI systems — RAG pipelines, memory-enabled conversational agents, and document intelligence.
I started building in 2022, ran paid client work and my degree in parallel, and completed a BS in Information Technology at the University of the Punjab in 2026. My method is learning by building — nearly everything on this page links to a deployed application, not a claim. One developer across the whole stack, with every build documented so a non-technical owner can run it after handoff.
