I’m looking for a developer to refine and extend an existing e-commerce website. I have uploaded a set of annotated screenshots that walk through every change I need, so please refer to those images before you bid. The upgrades span several parts of the site—from freshening up specific interface components, to tightening our payment-gateway flow, to improving how the product catalog is handled in the admin panel. Each item is clearly flagged in the pictures with notes on behaviour, layout, or data handling expectations. What I need from you: • Implement every change shown in the attachments exactly as described. • Keep current functionality intact while updating the affected areas. • Deliver clean, well-commented code so future maintenance is straightforward. • Test thoroughly on both desktop and mobile browsers; no regression issues. The project is fairly self-contained; once you review the screenshots you’ll see the scope is clear and finite. If anything in the images is ambiguous, let me know early so I can clarify.
