Enterprise Headless Storefront

2026 - PresentFrontendHeadless Commerce

Confidential Enterprise Client | via Aigital Technologies

The storefront needed a modern frontend foundation that could improve the customer experience while making checkout, rendering, SEO, and backend integration easier to scale.

Project Overview

This is an in-progress B2C ecommerce migration where an existing Magento storefront is being rebuilt into a headless architecture, with Next.js on the frontend and SAP OCC as the backend commerce layer. The goal is not just to modernize the stack. It is to make the buying experience faster, cleaner, and easier to scale as the storefront grows.

Current Focus

Headless Build

Frontend being rebuilt outside a legacy templated storefront model

Sole Frontend

Owning both the UI/UX direction and the frontend architecture

Checkout Rethink

Improving how payment, delivery, and conversion-critical steps work together

Scalable Foundation

Rendering, SEO, and data-flow decisions being made early instead of patched later

The Problem

Product Problems

  • The storefront needed a fresher, more guided customer experience.
  • Important journeys like homepage discovery, product browsing, and checkout needed clearer structure.
  • Mobile experience needed stronger attention from the start, not as a later adjustment.

System Problems

  • A headless storefront has more frontend ownership, which means more chances to create chaos if the foundation is weak.
  • Rendering, caching, SEO, checkout, and API boundaries all needed to be thought through together.
  • Without a clear architecture, the frontend could easily become hard to scale and harder to maintain.

Role & Ownership

I am the frontend architect on this project, and I am also handling the UI/UX side. That means I am not just implementing screens. I am helping shape how the storefront should feel for customers, how the frontend should be structured behind the scenes, and how complex commerce flows can stay clear as the project grows.

What I'm Building

1. Frontend Foundation

  • Structuring the storefront in a feature-first way instead of letting everything collapse into route files.
  • Creating a frontend foundation that can support product, cart, account, checkout, and content without turning messy.
  • Making the architecture understandable for future developers, not just workable in the moment.

2. Headless Architecture Decisions

  • Defining clear boundaries between browser code, BFF routes, and backend commerce systems.
  • Making sure the frontend is not leaking backend complexity into every component.
  • Planning data flow intentionally instead of solving each API call in isolation.

3. Rendering Strategy

  • Deciding which pages should be server-rendered, cached, or client-driven based on what the customer actually needs.
  • Keeping SEO-heavy pages different from personalized flows like cart, account, and checkout.
  • Preventing performance and freshness problems before they become launch issues.

4. Checkout Experience

  • Working on a cleaner checkout flow across delivery, shipping, payment, and place-order states.
  • Handling multiple payment paths without letting the checkout feel stitched together.
  • Keeping the experience conversion-focused while still respecting security and backend constraints.

5. UI/UX Direction

  • Improving how customers move through the storefront, especially on mobile where most ecommerce behavior happens.
  • Shaping pages so that the interface is clearer, more guided, and easier to act on.
  • Balancing modern visual design with practical ecommerce behavior.

6. SEO, Performance, and Quality Guardrails

  • Making SEO, metadata, and route behavior part of the system from the beginning.
  • Setting performance expectations around Core Web Vitals instead of relying on vague “optimize later” thinking.
  • Putting guardrails in place so the codebase can stay healthy as more features are added.

Why Headless Matters Here

More Frontend Ownership

In a headless build, the frontend owns much more of the customer experience, so the architecture has to be stronger.

More UI Responsibility

Design decisions, flow clarity, and conversion logic are no longer hidden inside a backend-driven template system.

More Need for Structure

If routing, checkout, SEO, and rendering are not decided carefully, the storefront becomes harder to scale very quickly.
