Basic E-Commerce Site Build

I need a straightforward e-commerce website built from scratch. The project is clearly a website development job, and the site will serve as a full online store rather than a blog or portfolio.

Core requirements
• An intuitive shopping cart so buyers can add, edit, and remove products before checkout.
• A clean, modern front-end that works smoothly on desktop and mobile.
• Admin access where I can add or edit products, prices, and images without touching code.

I’m open to your preferred stack—whether you favor Shopify, WooCommerce, custom PHP, or a lightweight headless setup—as long as the final store is easy for me to maintain. Please factor in essential security best practices and SEO-friendly structure.

When you respond, briefly outline:
1. Your recommended platform or framework.
2. Examples of e-commerce sites you’ve built with a shopping cart.
3. A rough timeline from kickoff to launch.

I’m looking for clean code, clear communication, and a working store ready for real transactions.
