About this gig

I build online stores that actually take money.


I architected and still maintain GeekyTech, a live NextJS

ecommerce platform serving 3,500+ customers and 23,000+

transactions with real inventory and real payments.


WHAT YOU GET

  1. Full storefront in NextJS, TypeScript and Tailwind CSS
  2. Product catalog, variants, search and filtering
  3. Cart and multi step checkout that does not lose orders
  4. Payment gateway with webhook signature verification
  5. Idempotency checks so nobody is ever charged twice
  6. Stock reservation so you never oversell
  7. Shipping rate and tracking integration
  8. Admin dashboard for products, orders and stock history
  9. Automated order emails
  10. Supabase PostgreSQL with row level security
  11. Deployed on Vercel with your domain


WHY THIS MATTERS

Most cheap store builds break at the payment layer. A

missing webhook check means an unpaid order marked paid.

A missing stock lock means two customers buying the last

item. I have already solved these in production.


HOW IT WORKS

1 Tell me your products, payment gateway and country

2 I confirm scope, timeline and price

3 Weekly milestones with a live staging URL


Message me before ordering so I can scope it properly.
