NextCommerse - Campus-First Commerce Platform

A campus-first e-commerce platform built for student entrepreneurs, small businesses, and local communities to sell and buy products with secure payments, smooth checkout, and order tracking.

Detailed write-up about the project, challenges, and solutions

I built this project as a campus-first marketplace, but designed it to scale beyond students to local sellers, micro-businesses, and growing online brands. The goal was to solve common informal-commerce problems: scattered orders, weak payment trust, and poor post-purchase visibility.

The platform supports complete commerce operations from product discovery to payment and order management, with architecture ready for wider market adoption.

Who it serves:

1. Student sellers and campus buyers.

2. Small local businesses needing a simple online storefront.

3. Growing merchants who need secure payments and reliable order workflows.

Core capabilities:

1. Product browsing, cart, and checkout.

2. Secure Paystack payment integration.

3. Guest cart with merge after login.

4. Order history and detailed order tracking.

5. Admin-ready management structure for operations.

Key engineering challenges solved:

1. Payment retry failures:

Introduced fresh transaction references for retries to prevent initialization conflicts.

2. Cart continuity:

Implemented guest-to-user cart merge to avoid losing selected items after authentication.

3. Reliable order visuals:

Stored image snapshots on order items and added robust fallback logic for display consistency.
