I'm Hafiz (Hafizur Rahman), a web developer from Dhaka, Bangladesh, building practical software for real businesses.
My work sits at the intersection of engineering and product thinking — mostly PHP, Laravel and MySQL on the back end, React and Next.js on the front. I've built business applications, POS systems, SaaS products, e-commerce integrations and API-driven systems.
I care about software that is understandable, maintainable and useful — not just software that works in a demo.
