Software engineering for eCommerce & Retail.

Commerce platforms built for Black Friday, not for the demo.

We build for retail and eCommerce teams — headless storefronts, unified inventory, POS integrations, and the internal tooling that keeps a multi-store operation running. We know the difference between software that works in a demo and software that holds up at peak.

Why Sonnet Code for eCommerce & Retail

The bar we hold ourselves to.

Peak-load-aware

We architect commerce systems around the Black Friday case, not the average Tuesday. Caching, queue depth, and DB connection limits are design inputs.

Omnichannel reality

Online, in-store, marketplace — we model inventory, customers, and orders so all three stay in sync without constant reconciliation work.

Conversion-focused

We measure Core Web Vitals on real devices. We know that every 100ms of LCP costs you percentage points on checkout.
