I need a full-stack developer to build a production-ready web application that handles every typical e-commerce flow and processes payments through the Dana e-wallet. The core pieces I have in mind are product listing, cart, secure checkout, order tracking, and an admin dashboard for inventory, pricing, and user management. Because this is strictly a web application, the interface must be fully responsive so customers on desktop or mobile browsers enjoy the same smooth experience. Payment is the critical point: Dana must be integrated natively so that customers can complete their purchase without being redirected. I am open to the underlying tech stack—whether you prefer React, Vue, or another modern front-end paired with Node, Laravel, Django, or similar on the back-end—as long as you can demonstrate that it is secure, scalable, and well-documented. Deliverables: • Fully functional web app with Dana payment gateway live in production • Source code in a private repo with a clear README for local setup and deployment • Database schema and migration files • Admin panel with role-based access control • Brief handover session or screencast walking through architecture, build, and deployment steps Please include a short outline of your proposed stack, estimated timeline, and any previous e-commerce work—especially projects involving non-standard payment gateways like Dana—so I can see how you would approach this build.
