I’m building a clean, mobile-first e-commerce website and want a freelancer who can take the current HTML / CSS / Bootstrap front-end concept and turn it into a fully functional store. The layout, product cards, and cart UI are already sketched out; what I now need is the code that makes everything work end-to-end. Core tasks • Wire up secure user authentication so shoppers can sign up, log in, and manage their accounts. • Add a fast product search that filters results in real time. • Integrate payments for Credit/Debit Card—Stripe or a comparable gateway is fine—and Bank Transfer. • Keep the UI lightweight and fully responsive across desktop, tablet, and phone. • Maintain clear, well-commented code so I can extend it later; I’m open to vanilla JS or a modest React layer if that simplifies state handling. Acceptance criteria 1. User can register, verify email, and sign in/out without page refresh errors. 2. Search returns accurate results in under 300 ms on a test dataset of 500 items. 3. Test purchases complete successfully with card and bank transfer sandbox accounts, and order data persists. 4. No layout shifts on screens from 320 px to 1440 px; scores 90+ on Google Lighthouse mobile. I’ll supply the product images, copy, and initial Bootstrap files; you provide the working pages, any backend endpoints or API stubs, and a short README for setup. If this sounds like your kind of build, let’s get started.
