E-commerce Engineering Partner

Headless storefronts, custom checkout, and conversion-focused engineering — Shopify, Commerce Layer, or fully custom.

E-commerce platforms ship a transaction every few seconds and break under load every Black Friday. We build commerce systems that survive the spikes, convert better in the funnel, and integrate cleanly with the catalogue, fulfilment, and finance systems behind them.

Where teams get stuck

The e-commerce problems we get called for.

Theme platform hit its ceiling

Shopify Liquid is fine until it isn't. Page Speed crashes, conversion drops on mobile, and every customisation is 'available on the next plan up'.

BFCM took the site down

Cache wasn't tuned for the traffic profile, the checkout queued, payment retries hit rate limits, and the team was firefighting on Black Friday at 3am.

Post-purchase is a black box

Order confirmation goes out, then nothing — no proactive shipping updates, no transparent returns flow, no way to upsell to existing customers.

Inventory + fulfilment + finance don't agree

Three different systems, three different views of the same truth. Reconciliation is a finance team's spreadsheet and an angry warehouse manager.

What we bring

How e-commerce engineering should look.

Headless commerce, properly

Next.js + Shopify Storefront API / Commerce Layer / commercetools. Page-speed wins, custom checkout, no platform tax on your conversion rate.

Conversion-engineered checkout

Sub-2-second checkout, address autocomplete, Apple Pay / Google Pay / Klarna / Affirm in one swipe, real-time tax, intelligent error recovery.

BFCM-ready infrastructure

Edge caching, CDN-first images, WebSocket-based queue, graceful degradation. Survives 50× traffic spikes without a fire drill.

Post-purchase platform

Tracking pages, returns flows, NPS, review collection, email + SMS lifecycle automation — all branded, all integrated, all yours.

Inventory + fulfilment integration

Direct sync with ShipStation / ShipBob / Easyship / your 3PL, NetSuite or Xero for finance, and a dashboard everyone trusts.

Personalisation without creepy

Smart bundles, abandoned-cart, segment-based recommendations — first-party only, GDPR-compliant, no third-party trackers.

FAQ

Common questions about e-commerce.

Do we have to leave Shopify?+

Not at all. Headless Shopify keeps your back office (catalogue, orders, fulfilment, finance) on the platform you know, while giving you full design and performance control on the storefront.

What's the typical performance lift?+

Going from a Liquid theme to a properly-built headless Next.js storefront typically lifts mobile Core Web Vitals from 'poor' to 'good' and conversion 10–25% on mobile. Numbers depend on starting point and category.

Can you handle BFCM the year of launch?+

Yes — we load-test against your historical peak × 5, tune CDN caching, and stand by during the launch weekend with on-call coverage. We've never had a customer take a brand-blocking outage on a peak.

Do you also build the marketing site?+

Yes — we usually unify the marketing site, content, and storefront on one Next.js app with shared design system. One stack, one deploy, one team.
