CASE STUDY // E-COMMERCE PLATFORM
Retail E-Commerce & Order Fulfilment Platform
A production e-commerce platform for a consumer electronics accessories retailer, covering smartwatches, cases, chargers, earphones, power banks, and cables. Customers browse, save, review, and pay online; staff manage products, orders, brands, and support from a permissioned back-office.

The Operational Bottleneck
The retailer was selling through scattered social media conversations with no central catalog, no online payments, and no way to track orders or follow up with customers. They needed a storefront that could take payments securely and a back-office their staff could actually run.
The Engineered System
We built a full-stack platform with a multi-level category and brand catalog, persistent carts, wishlists, verified reviews, and Paystack checkout. Customers can sign up with email or Google. Staff get granular permissions (products, orders, brands, support), every admin action is written to an audit log, and refresh-token rotation, account lockout, and Redis-backed rate limiting harden authentication.
