E-commerce

E-commerce encompasses the buying and selling of goods and services over the internet, including online storefronts, marketplaces, subscription services, and digital product delivery. It covers the entire transaction lifecycle from product discovery and browsing through cart management, payment processing, order fulfillment, and post-purchase support.

E-commerce platforms range from hosted solutions like Shopify and BigCommerce that handle infrastructure and provide pre-built storefronts, to headless commerce platforms like Commercetools, Medusa, and Saleor that provide backend commerce APIs while allowing custom front-end development. The choice depends on the need for customization, scale, and control over the user experience.

For web development, e-commerce projects involve distinct technical challenges. Product catalogs require efficient search and filtering across potentially millions of SKUs. Payment processing demands PCI compliance and integration with gateways like Stripe or Adyen. Checkout flows must minimize friction while handling tax calculation, shipping options, and inventory validation. Performance is directly tied to revenue, as each second of additional load time measurably reduces conversion rates.
