Built a complete e-commerce platform for a gaming and desk-setup store, covering the full customer journey: browsing, cart, checkout with Stripe, and order tracking. Includes an admin dashboard for managing products and orders, plus a few standout features — a budget-based setup builder that proposes a full gear list, a part-compatibility checker, and a search bar that understands natural phrases like "wireless mouse under 300 TND." Built solo with Next.js, NestJS, PostgreSQL and Stripe, with automated tests covering the core logic and checkout flow.
