Production-ready online store with product catalog, cart, and Stripe-powered checkout, built for speed, clean UX, and maintainable growth.
Payments
Secure checkout flow using Stripe (session-based checkout + order handling)
UX
Fast product browsing with responsive, mobile-first UI
Architecture
Reusable UI components and clean state boundaries for cart/checkout
Stack
Next.js, React, TypeScript, Tailwind CSS, Stripe, Supabase
Use Cases
Inventory & Catalog Management
Admin-managed product catalog with categories, galleries, and inventory control.
Checkout & Sales Operations
Secure Stripe integration with order persistence, payment tracking, and analytics-ready data.
Backoffice CMS
Role-protected admin interface to manage homepage content (hero, banners, settings) and review contact messages.
End Users
Browse categories, view product details, manage wishlists, and maintain a persistent shopping cart.
Key Metrics & Impact
Secure Data Access
Granular RLS policies ensure public read-only access to catalog data, while authenticated users can only access their own carts and orders.
Operational Efficiency
Centralized admin panel enables full CRUD management of products, categories, banners, settings, and orders from a single interface.
Reliable Checkout Flow
Stripe webhooks ensure accurate order persistence and automatic synchronization after successful payments.
Optimized Media Pipeline
Automated image processing pipeline (HEIC → JPG conversion, dynamic optimization) reduced image payload size and manual asset handling.
Technical Challenges Solved
Access Control & Authorization
Next.js middleware enforces authenticated sessions and admin role validation before granting backoffice access.
Stripe Synchronization
Webhook-driven processing of checkout.session.completed events to persist orders and reconstruct purchased items reliably.
Media Optimization & Cleanup
Custom pipeline to manage Supabase Storage buckets, clean outdated assets, and generate optimized derivatives.
Relational Data Integrity
Complex PostgreSQL RLS policies ensure strict separation between public catalog data, user carts, and order history.
