À propos de moi
Hi, I'm Sajjad, a full-stack web developer from Pakistan. I build websites and platforms for coaches, consultants, course creators and small businesses: booking and enquiry forms, client or student accounts, payment flows and admin dashboards you can manage yourself. My recent project is a complete online course platform with student dashboards, enrollment, payment verification and an admin panel. I work in PHP, MySQL, JavaScript, React and Node.js, agree scope and price in writing, and update you every few days. Message me before ordering and I'll suggest the right package.... Plus d’infos
