Deterministic Distributed Architecture
0.00% Oversell RateLegacy commerce plugins fail during high-concurrency traffic spikes. We replace fragile third-party apps with event-driven webhook pipelines, cryptographic HMAC verification, and sub-millisecond Upstash Redis mutex locks.
Applied Multi-Model AI Workflows
12,000 SKUs / HourWe embed Anthropic Claude 3.5 Sonnet and Google Gemini 1.5 Pro directly into merchant catalog operations—automating 13-tag Etsy semantic taxonomy, Amazon A+ schema synthesis, and multi-market localization under strict zero-data-retention policies.
Principal-Only Engineering Execution
Direct Architect AccessWe do not employ junior account managers or outsource development. Every engagement is architected and shipped directly by principal systems engineers in shared Slack channels with weekly production releases.
Four Core Technical Disciplines.
Modular commerce infrastructure engineered from first principles—designed to replace brittle plugin stacks.
Headless Storefronts & Edge SSR
We engineer custom Next.js App Router and Shopify Hydrogen storefronts deployed across 300+ global edge locations. Instant route transitions, zero third-party script bloat, and bespoke mobile conversion flows.
Multi-Channel Inventory Synchronization
Event-driven webhook mesh maintaining real-time inventory parity across Shopify Plus, Amazon SP-API (FBA/MCF), and Etsy v3 using distributed Upstash Redis atomic locks.
Applied AI Catalog & Rust Functions
We integrate Anthropic Claude 3.5 Sonnet and Google Gemini 1.5 Pro for automated multi-market taxonomy and SEO synthesis, paired with WebAssembly Shopify Functions for B2B volume pricing.
Core Web Vitals & Clean-Room Rewrites
Every 100ms of main-thread blocking degrades checkout conversion. We audit and strip out legacy tracking tags, rewriting core theme templates in clean Liquid v2 to guarantee 95+ mobile scores.
Deterministic Sync & AI Pipeline.
Inspect the four architectural stages that power our multi-channel synchronization and catalog reasoning engine.
Distributed Atomic Redis Mutex
During high-velocity product drops, thousands of concurrent checkouts compete for the same SKU. Our engine acquires a sub-millisecond atomic lock in Upstash Redis to guarantee zero overselling.
- Lock Primitive
- Redis SET NX PX 1500ms
- Acquisition Latency
- <1.0 Millisecond
- Contention Strategy
- Jittered Exponential Backoff
export async function acquireSkuLock(sku: string, orderId: string): Promise<boolean> {
const lockKey = `lock:inventory:${sku}`;
const lockToken = `order:${orderId}:${Date.now()}`;
// Atomic reservation with 1500ms automatic safety release
const acquired = await redis.set(lockKey, lockToken, "NX", "PX", 1500);
if (!acquired) {
await retryQueue.enqueue({ sku, orderId, backoffMs: 120 });
return false;
}
return true;
}Verified Merchant Outcomes.
“JB.er migrated our monolithic Liquid theme to Hydrogen edge servers. Our cart drop-off fell from 68% down to 34%, and checkout conversion jumped by 184% in the first quarter.”
“Their Amazon SP-API and Etsy sync automated our entire multi-channel inventory. We have managed 12,000 active SKUs across Q4 peak season with zero overselling incidents.”
“JB.er built custom Rust Shopify Functions for our tiered volume bundles and Claude 3.5 catalog pipelines. Mobile PageSpeed increased from 38 to 99, transforming our unit economics.”
