About


Qamar Ul Din Hamza

I have been building web systems professionally since 2015 — WordPress plugins, WooCommerce engines, payment systems, then headless builds with Next.js. Today that foundation carries my main work: AI automation and integration systems that survive production.

Proof, not promises: a live 12-agent AI lead generation system (Claude API, Apify, Supabase) runs my own prospecting end-to-end — scanning, scoring, writing, sending, following up — for about $4 a month. The same engineering goes into every client system I ship.

My strongest platform is still WordPress and WooCommerce: 30+ custom plugins live on commercial sites, subscription and billing systems processing serious monthly revenue, and stores optimised to 90+ PageSpeed. These are systems where bugs cost money — they have to work.

I work independently. No team, no middleman, no project manager. You get me — writing the code, reviewing every AI-assisted line before it ships, answering your questions directly. That is the model behind 100% job success across 140+ projects and zero failed contracts in 10 years.
