E-Commerce Development for Shopify & Custom Storefronts

E-Commerce Development

E-commerce development is the discipline where performance has the most direct, measurable revenue impact. Research shows a 100ms increase in page load time reduces conversion rates by 1–2%. A single additional step in the checkout flow reduces completion rates by an estimated 10%. Every architectural decision in our e-commerce projects is evaluated against its effect on conversion — not just technical correctness.

Our e-commerce work spans three approaches: custom-built storefronts on Next.js with headless commerce backends (maximum control, maximum performance), Shopify development for clients who need a managed platform with built-in logistics integrations, and WooCommerce for businesses already in the WordPress ecosystem. Platform selection is driven by your catalog complexity, checkout requirements, and long-term operational needs — not by which platform is faster to build.

Payment integration is handled through Stripe as the primary processor — supporting card payments, Apple Pay, Google Pay, and subscription billing from a single integration. For Latin American markets, we integrate local payment methods: PIX, Boleto Bancário, and local card acquirers. Every payment flow is tested against failure states — declined cards, network timeouts, and webhook delivery failures — because checkout failure is the most expensive bug in e-commerce.

Mobile-first is an operational requirement. Over 70% of e-commerce traffic arrives on mobile devices, and checkout abandonment on mobile reaches 85% vs. 73% on desktop. We build checkout flows for one-handed operation on small screens: minimal form fields, persistent cart state across sessions, and payment methods that bypass manual card entry. Mobile checkout is a distinct engineering problem — not a responsive design afterthought.

We have built e-commerce systems for fashion brands, specialty food retailers, B2B industrial suppliers, and digital product sellers — each with different catalog structures, fulfillment workflows, and customer acquisition channels. A B2B industrial supplier with 10,000 SKUs and net-30 payment terms is a fundamentally different system than a DTC brand running limited-edition drops. Platform and architecture are chosen accordingly.

We do not use page builders, drag-and-drop tools, or theme frameworks for production e-commerce. Every component is purpose-built for performance, auditability, and long-term maintainability. Page builder output produces bloated HTML and JavaScript payloads that cannot be optimized. When your storefront needs to load in under 2 seconds on a 4G connection, the build tool matters.
