Retail & e-commerce
Storefronts, order management, inventory sync and customer messaging — engineered for peak-season load rather than for a quiet Tuesday.
Retail load is not evenly distributed. A system that comfortably handles a normal week can fail entirely in the first ten minutes of a sale, and that failure is uniquely expensive — you lose the revenue, the acquisition spend that drove the traffic, and the customers who now associate your brand with an error page.
The second defining feature is that inventory truth is hard. Stock lives in a warehouse system, a storefront, a marketplace listing and possibly a physical shop, and every one of them believes it is authoritative. Overselling is a customer-service problem; underselling is invisible lost revenue.
Add marketplace channels, returns handling, and customers who expect proactive order updates on their preferred channel, and the operational picture gets complicated quickly.
Five recurring problems.
The site falls over during sales
Usually not raw capacity but a specific bottleneck — an unindexed query, a synchronous call to a slow third party, or a cache that stampedes. Load testing finds them before customers do.
Stock levels that aren't true
Overselling on a marketplace, or hiding stock that exists. Fixing it means deciding what the source of truth is per channel and syncing deliberately rather than on a schedule.
Order management sprawl
Orders arriving from a storefront, marketplaces and phone, tracked across three systems and a spreadsheet. Consolidation is usually the highest-return project.
Customers asking where their order is
Proactive order and delivery updates over the channels customers actually read remove most of this inbound volume.
Slow storefronts losing conversions
Mobile page speed is directly commercial in retail. A performance rescue is frequently the cheapest conversion improvement available.
The services that carry most of our retail work.
Web Development
Storefronts and replatforming built to Core Web Vitals — where page speed converts directly into revenue.
Enterprise Integration
Keeping storefront, ERP, warehouse, marketplaces and carriers in agreement about stock, orders and pricing.
Communication Platform
Order confirmations, dispatch and delivery updates, abandoned-cart recovery and campaigns over WhatsApp, SMS and RCS.
Cloud & Infrastructure
Capacity planning, load testing and autoscaling ahead of peak — plus the cost work to avoid paying peak prices year-round.
Data & Analytics
Margin by product, channel profitability and returns analysis — the numbers that decide what to stock and what to stop.
What we do in the run-up to a sale. The work that matters happens weeks before, not on the day.

Model the load
Agree the expected peak from last year's data plus this year's marketing plan, then load test against it — not against a comfortable number.

Fix what breaks
Load testing always finds something. Query optimisation, caching, and removing synchronous calls to third parties that will be slow when everyone else is also hitting them.

Scale and rehearse
Autoscaling configured and tested, a rehearsed rollback for every planned change, and a code freeze date agreed and honoured.

Watch it live
Engineers on call watching real-user metrics, with pre-agreed degradation options — what gets turned off first if things get tight, decided while everyone is calm.
The most valuable thing on that list is deciding in advance what you'd sacrifice. Every retailer has something they'd rather disable than lose checkout.
For most retailers, a platform like Shopify or WooCommerce with careful configuration is the right answer, and we'll say so rather than sell a build. Custom becomes justified when your fulfilment or pricing logic genuinely doesn't fit a platform, or when the storefront experience is itself the differentiator.
