E-Commerce Development

Headless commerce. Custom marketplaces. Built to convert and scale.

Off-the-shelf e-commerce platforms cap your growth. When you need custom pricing logic, complex inventory, B2B workflows, or marketplace features, you need custom development — not more plugins fighting each other.

The challenge

Shopify and WooCommerce are fine until they aren't. Custom pricing rules, complex B2B workflows, marketplace splits, and real-time inventory across multiple warehouses break every plugin-based solution. At that point you're paying for a platform you've outgrown.

Frequently asked questions

When does it make sense to go headless vs Shopify?
Go headless when: you need custom checkout logic Shopify can't support, you have complex B2B pricing, you're building a marketplace, you need sub-second performance, or you want to own your tech stack. Stay on Shopify when: you're selling straightforward D2C products, your team needs to manage the store without developers, and you're under $5M revenue.
Can you build a multi-vendor marketplace?
Yes — HomeBrigadier is a two-sided marketplace I built connecting homeowners with verified service providers: real-time booking, Stripe payments, a reviews system, and provider dashboards. Marketplace architecture is more complex than a standard store — vendor onboarding, per-vendor listings, and payout flows all add scope — so plan for a meaningfully longer build than a single-seller storefront.
How do you handle Strong Customer Authentication (SCA/3DS2) for EU?
SCA is required for European card payments. I implement 3DS2 correctly through Stripe (automatically handles authentication flows), ensure your checkout doesn't break on SCA challenges, and implement proper exemption logic for low-risk transactions and recurring payments.
Can you integrate with our existing ERP or warehouse system?
Yes — I integrate with ERPs such as NetSuite, SAP Business One, and Cin7, as well as custom warehouse APIs. This typically involves bi-directional inventory sync, order routing, and fulfillment status updates. Complexity and timeline depend on your ERP's API quality.
What's your approach to e-commerce performance?
Next.js with static generation for product pages, Algolia or Typesense for search (not database queries), Redis for cart and session, Cloudflare for CDN and edge caching, optimised images via next/image, and Core Web Vitals monitoring. Target: LCP under 1.5s, INP under 200ms.
