Shopify, headless commerce and custom storefronts engineered for revenue.

About E-commerce Development

E-commerce is one of the few places where engineering quality maps directly to revenue you can count. A second shaved off product-page load, a checkout step removed, a search that actually understands synonyms, a stock figure that is accurate — each of those moves conversion rate, and conversion rate moves the top line immediately. That makes commerce work satisfying to measure and unforgiving to get wrong.

We work across three models and are honest about which fits. Shopify and Shopify Plus for merchants who want operational simplicity and a mature app ecosystem, where we focus on theme performance, custom app development and checkout extensions. Headless commerce — a commerce engine such as Shopify, Commercetools or Medusa behind a custom front end — when brand experience, content-commerce blending or extreme performance matter more than out-of-the-box convenience. Fully custom platforms only where the business model genuinely demands it: unusual pricing logic, complex B2B contracts, marketplace mechanics, or regulated fulfilment.

The engineering priorities are consistent regardless of model. Product and collection pages are server-rendered for Core Web Vitals and organic visibility, with structured Product and Offer data so listings earn rich results. Checkout is stripped to the minimum viable friction, with express wallets, address autocomplete and honest shipping estimates surfaced before the final step. Catalogue, inventory, pricing and order data are integrated bidirectionally with your ERP or OMS so the store never shows a number the warehouse would dispute.

Post-launch we run a continuous optimisation loop: funnel instrumentation, structured A/B testing on the pages that carry the most revenue, merchandising and search relevance tuning, and peak-season load rehearsal well before peak season arrives.

Why it matters

What you get

Speed that converts

Server-rendered product and collection pages, image and script budgets, and edge caching — because load time is a conversion lever, not a vanity metric.

Checkout friction removed

Fewer steps, express wallets, address autocomplete and transparent shipping and tax shown before the final screen.

Rich results in search

Product, Offer, Review and BreadcrumbList structured data, clean faceted-navigation URLs and disciplined canonical management.

Systems that agree with each other

Bidirectional ERP, OMS, PIM and 3PL integration so inventory, pricing and order status are consistent everywhere.

Built for peak

Load-tested against your projected Black Friday volume, with caching, queueing and autoscaling proven before the day rather than during it.
