About
Full-stack developer. One owner end to end.
I'm Mehdi Haider — Top Rated freelance full-stack developer based in Karachi, Pakistan. Bachelor of Computer Science (IQRA University). 17+ years building web apps, mobile apps, WordPress platforms, CRM systems, and compliance-ready software for clients worldwide since 2009.
The short version
I build software like an owner, not a ticket queue.
Most freelancers specialize in one slice. I take full ownership: product thinking, architecture, UI, backend, mobile, integrations, deployment, and the boring details that keep systems alive after launch.
That model works because clients get one accountable person — no handoffs, no “that’s another team’s job,” and no surprise dependency chain. You talk to the person writing the code.
I've worked across healthcare, education, eCommerce, SaaS, and internal ops tools. Some engagements last months. A few have lasted more than a decade. Longevity is the best review.
