Project Overview
Jucko is a modern e-commerce platform built to provide a smooth, reliable shopping experience across devices. I developed both backend and frontend modules — handling user authentication, product management, order processing, and payment integration. The system was engineered for scalability, real-time updates, and seamless checkout flow using Node.js, React, and MySQL.
Challenges and Solutions
Maintaining Cart Synchronization
Ensuring that cart changes across devices (mobile/web) stayed synchronized in real-time presented performance and data consistency issues.
Database Query Optimization
Product filtering and searching caused slow response times with large datasets in early versions.
Payment Validation & Error Handling
Managing transaction verification and retries when payments failed required robust API handling.
UI Consistency Across Screens
Balancing aesthetics and usability across hundreds of product cards and views required modular, responsive design components.
Real-Time State Synchronization
Leveraged Socket.io and Redux Toolkit to manage shared state, keeping the cart updated instantly across sessions.
Query Optimization & Caching
Added database indexes, implemented query caching, and refactored Sequelize queries for faster retrieval times.
Robust Payment Workflow
Integrated Paystack’s transaction verification endpoint and error handling system to ensure payment integrity and user transparency.
Modular Responsive Components
Used Tailwind and reusable React components to maintain design consistency, accessibility, and responsiveness on all devices.
