About
Faraz Hussain
Shopify developer, web engineer & AI automation consultant based in Karachi. I build storefronts, ship agents, and write the playbooks I wish I’d had earlier.
Bio
Over 6+ years and 50+ projects, I’ve worked as a full-stack architect and technical lead for startups and enterprise clients. Day to day that means custom Shopify themes, high-performance React and Next.js sites, and AI agent / RAG systems that actually make it to production.
I’m based in Karachi, Pakistan. Recent roles include Senior Web Developer at Holidays Maker and Senior Web Engineer at Vibe & Scale, plus Shopify builds for merchants across travel, nutrition, dental, and multi-market retail.
This Playbook site is the public notebook: free calculators, field guides, and how I ship— separate from client delivery on farazhussain.com.
