Lahore, Pakistan - 1:17 pm local time
I architect production-ready AI SaaS platforms, full stack web applications, and Shopify solutions using Django, FastAPI, Ruby on Rails, React, Next.js, and Node.js including a Built for Shopify-qualified app running on long-term retainer. Over 6+ years and 27+ Upwork contracts, I've helped companies serve 10,000+ users, improve backend performance by 40%, and automate workflows that saved teams 10–40 hours a week.
I don't just ship features I build scalable systems with real payment flows, OAuth, webhooks, AI pipelines, and AWS infrastructure that businesses can actually grow on.
