Real example: Facelees, an e-commerce platform I built for a local business owner in Dhaka, Bangladesh. Customers browse, search, and check out via Cash on Delivery with no registration required. On the admin side: full product catalog CRUD with image upload, hero banner management, an order dashboard with a pending→confirmed→shipped→delivered pipeline, and admin-only inventory control — restricted to a hardcoded whitelist, no public signup risk. Deployed on Cloudflare for edge caching, CDN, and security.
