Codescap Commerce: Modern Omnichannel E-Commerce Suite
A full-stack monorepo e-commerce solution pairing Next.js customer web storefronts with native React Native mobile apps and atomic inventory orchestration.
Key Project Metrics and Results
01 / System Overview
Background & Problem Space
Growing retail brands require unified customer experiences across web and mobile without fragmenting their product inventory, order queues, or customer address books. Codescap Commerce is an end-to-end e-commerce monorepo platform designed for high conversion, rock-solid stock consistency, and seamless administrative control.
02 / Technical Challenge
Core Bottlenecks
Modern shoppers expect sub-second page loads on web and smooth native interactions on iOS and Android. Behind the scenes, flash sales can cause catastrophic overselling if stock decrement logic is not executed in atomic multi-document transactions.
03 / Engineering Solution
Architectural Approach
We built a monorepo platform that unites a Next.js customer storefront, an Expo-powered iOS/Android app, an operational admin console, and an Express API sharing a unified TypeScript type system. Checkout operations run inside MongoDB replica-set transactions to ensure zero inventory overselling.
04 / Architecture Breakdown
Key Engineering Decisions
Turborepo-orchestrated monorepo housing Next.js web applications, Expo mobile applications, and an Express.js API, sharing schema validation and utility libraries.
Atomic Stock Transactions: Checkout decrement queries run in multi-document transactions so two users purchasing the last item never cause stock anomalies.
Shared Schema Contract (@repo/types): Product, Variant, Cart, and Order schemas are defined once in Zod and imported by API, Web, and Mobile apps.
Hybrid Static & Dynamic Rendering: High-traffic product categories are pre-rendered statically for SEO and hydrated dynamically for real-time stock levels.
