Software built and proven for commerce that can't go down at peak.

Storefronts, marketplaces, AI-powered search and recommendations, and checkout systems, built and load-tested for the traffic spikes that make or break a quarter.

What building for e-commerce actually requires.

E-commerce platforms have measurable failure costs. A checkout defect during a peak event translates directly to lost revenue. A search bug that surfaces wrong products affects conversion across the catalog, so the storefront, search, and checkout have to be engineered for both everyday traffic and the spike.

Peak events compound the risk. Black Friday, holiday seasons, flash sales, and product launches concentrate revenue into windows where the system must hold. The architecture needs headroom modeled on last year's traffic, not synthetic benchmarks, and the QA program has to prove that headroom before the event, not during it.

The catalog itself adds build and testing surface. Promotions stack in ways that create edge cases. Currency handling, tax calculation, shipping calculation, and inventory holds all have failure modes that require explicit design and explicit scenario coverage.

What we build.

Storefronts and marketplaces, headless commerce, multi-warehouse fulfillment, and partial-shipment logic built in.

AI-powered search and recommendations, semantic product search, personalization, and merchandising built and evaluated.

Checkout and payments engineered for peak, promotion stacking, tax, currency, and shipping rules handled correctly.

Infrastructure sized and proven for peak events, traffic-modeled load testing grounded in production patterns.

Where it breaks without care.

Systems pass load tests but fail under real peak traffic shape, because the architecture and the test scenarios were never modeled on actual patterns.

Edge cases in promotion stacking, address validation, or payment handling get discovered live, driving silent revenue loss.

Search results degrade after catalog or ranking changes. The drop gets caught through revenue, not through testing, because the search relevance work is treated as a one-time build instead of an ongoing concern.

Race conditions on inventory holds, stale prices in cache, and multi-warehouse shipping logic produce hard-to-reproduce bugs when concurrency isn't designed for up front.

How we deliver it.

Catalog, search, checkout, promotions, and fulfillment surfaces built and mapped with risk tiers from the architecture stage.

Checkout and core catalog flows engineered with automated coverage wired into CI from day one.

Traffic-modeled load testing grounded in production patterns and peak event history, run before the event, not after.

Edge-case scenarios for promotion stacking, currency, tax, and shipping rules built and tested explicitly.

One-page readiness brief delivered before each peak event with risk update and recommendations across build and QA.

Industry focus areas.

End-to-end checkout coverage with payment, address, shipping, and promotion edge cases built and tested together.

Traffic-modeled load testing grounded in production patterns and prior peak event history.

AI-powered search relevance, personalization, and catalog scale-up built and evaluated on a regression suite.

Promotion stacking edge cases, currency handling, tax calculation, shipping rule validation.

Race condition testing on inventory holds, multi-warehouse shipping, and partial fulfillment.

Core Web Vitals tracking on conversion-relevant pages with release correlation and regression alerting.

Tools and technologies.

E-commerce programs are graded on three things: how fast the storefront loads, whether checkout holds under load, and how fast a regression in search or promotion logic gets caught. The stack below spans all three.
