AuraNode (Organic Harvest)

AuraNode is a scalable, SEO-optimized e-commerce platform built specifically for the "Organic Harvest" brand. Leveraging Next.js App Router for server-side rendering and Supabase for a robust backend-as-a-service, it delivers exceptional Core Web Vitals and seamless inventory management.

Traditional e-commerce platforms (like Shopify or WooCommerce) often suffer from slow page load speeds and limited developer flexibility when building custom, multi-channel inventory pipelines. The client required a bespoke solution capable of handling high traffic spikes during seasonal sales without degradation in performance.

• Achieve perfect 100/100 Lighthouse scores for SEO and Performance.
• Implement strict data security using Row-Level Security (RLS).
• Create a real-time admin dashboard for inventory management.

High-Level Architecture

A fully serverless architecture. The Next.js frontend is deployed on Vercel, utilizing React Server Components (RSC) to fetch data directly from the Supabase PostgreSQL database at the edge.

System Components

• Frontend: Next.js 14+ (App Router), React, Tailwind CSS.
• State Management: Zustand (for complex cart logic).
• Backend/DB: Supabase (PostgreSQL, Auth, Storage).
• Email/Comms: Resend API.

• Backend/DB: Supabase (PostgreSQL, Auth, Storage).
• Email/Comms: Resend API.

• Row-Level Security (RLS): Implemented strict RLS policies in Supabase ensuring users can only read/write their own cart and order data, while admins have elevated privileges.
• promo_codes: Tracks generated coupons with hashed values, max_uses, use_count, and expires_at TTL parameters.
• email_queue: Decoupled asynchronous job table for processing scheduled drip campaigns.

• Authentication: Supabase Auth with magic links and OAuth providers.

AuraNode implements four core serverless engines:

1. AI Smart-Bundling: Cross-references real-time cart state against the catalog to curate a 1-click bundle with a precise 15% discount.
2. Ghost Revenue Retriever: Vercel Cron jobs poll Supabase for status = 'draft' orders older than 24 hours, generate single-use cryptographic coupons, and dispatch recovery emails via Resend.
3. Automated Drip Campaigns: Employs an email_queue table to schedule and dispatch review requests (+7 days) and loyalty discounts (+14 days).
4. Cryptographic Coupons: Derives promo codes using crypto.randomUUID() + HMAC-SHA256, storing them with a strict max_uses constraint to prevent brute-forcing.

Fully serverless architecture deployed to Vercel. Backend PostgreSQL database managed via Supabase. Cron jobs strictly authenticated via header-injected CRON_SECRET tokens.

• Authentication: Supabase Auth with magic links and OAuth providers.

• Challenge: Managing complex client-side state (the shopping cart) alongside Server Components.
• Solution: Adopted Zustand for lightweight, un-opinionated client-side state management, passing only necessary dehydrated state from the server to the client.

• "Why did you choose Zustand over Redux or React Context for this project?"
