Project Overview
The Problem
Most e-commerce platforms available to small and mid-size businesses either lack flexibility for multi-payment support or provide poor developer control over the shopping experience. Managing inventory, orders, and customer data through separate tools adds operational overhead and degrades the customer experience.
The Solution
I built a complete e-commerce platform from the ground up — a NestJS backend with a React.js frontend — covering the full shopping lifecycle from product discovery to order fulfilment. The platform integrates multiple payment gateways, a review system tied to verified purchases, and a filter-heavy shop page with URL-synced state, making it easy for users to find products and for admins to manage operations from a dedicated dashboard.
Target Audience
Small to mid-size online retailers and their customers who need a reliable, feature-complete shopping experience with flexible payment options and transparent product reviews.

Why This Stack?
NestJS gave me a scalable, opinionated backend architecture well-suited to the modular nature of an e-commerce API. React.js and TanStack Router enabled robust URL synchronisation for complex shop filters without sacrificing the user experience. Supporting Paystack, Stripe, and NowPayments ensured the platform could serve both local Nigerian customers and international buyers, including crypto payment options.
