Backend Developer specialized in Python and Django with over 4 years of experience building reliable, scalable, and production-ready backend systems. I focus on designing clean RESTful APIs, implementing complex business logic, and building secure, maintainable backend architectures. I have worked on multiple real-world systems including POS, ERP, LMS, clinic reservation, and e-commerce platforms. My experience includes real-time features using WebSockets, role-based access control, reporting and PDF generation, and integrating thermal printers for operational systems. I enjoy solving backend problems that require strong data modeling, transactional consistency, and performance-aware design, and I am always motivated to build backend services that directly support real business needs and user workflows.
