Technical Hurdles

The Challenge

Building a consumer-facing e-commerce platform that syncs real-time garment stock with physical store POS inventory while maintaining sub-second page load times and 60fps mobile browsing.

Real-Time Multi-Channel Inventory Sync

Preventing overselling when physical store POS and online customers purchase identical apparel stock simultaneously.

Sub-Second SSR & Mobile E-Commerce UX

Delivering high-resolution product visuals and dynamic filters without slowing Core Web Vitals or initial paint times.

Engineering Approach

Our Solution

Architected a unified Supabase database schema with serverless API hooks, aggressive client caching with TanStack Query, and optimized Next.js App Router server components.

Atomic Supabase Inventory Transactions

Integrated Postgres database locks and triggers to ensure accurate stock deductions across physical POS and online channels.

Next.js 16 & Turbopack SSR Pipeline

Implemented server-side data loading and responsive WebP image pipelines for instant initial paints.
