About
Qamar Ul Din
Hamza
I’ve been building WordPress systems professionally since 2015 — starting with theme work and plugin customisations, growing into complex plugin architecture, payment systems, and now headless builds with Next.js and Astro, plus AI automation.
My strongest area is WooCommerce: subscription engines, payment gateways, B2B pricing, checkout optimisation, and migrations. 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, reading your briefs, answering your questions directly. That’s the model that lets me maintain 100% job success after 147+ projects.
