This project involved diagnosing and fixing complex backend issues in a Laravel + Bagisto eCommerce system.
The main challenge was that category-wise product listings were not displaying after bulk CSV uploads due to query misconfiguration and recursive category mapping errors.

I analyzed and refactored the getCategoryProducts() and getAll() methods to ensure:

Proper recursive category filtering (including subcategories)

Clean and optimized SQL joins

Fixed alias duplication (Not unique table/alias: 'product_categories')

Resolved model hydration issue causing Call to a member function videos() on null

Restored full product visibility on the frontend

The fix ensured that bulk uploaded digital products now appear correctly across category pages — improving reliability and backend performance.

Fixing Ecommerce Error

I designed and developed a fully dynamic, AI-powered website for The Blissful Life Report, a unique platform that provides personalized blueprints for abundance, alignment, and awakening. The system decodes hidden life patterns through universal energies, numbers, vibrations, and cosmic alignments, and then generates customized reports to transform health, wealth, relationships, and spiritual growth.

The project included building a custom CMS (Content Management System) from scratch in Laravel, enabling admins to easily manage dynamic content, user data, and personalized reports. The platform integrates AI (ChatGPT API) to generate insightful, personalized interpretations and recommendations based on user input, ensuring each report feels tailor-made.

For monetization and seamless user experience, I integrated Razorpay payment gateway for secure transactions. After successful payment, users automatically receive their AI-generated reports in a clean, user-friendly HTML format, with t

I developed a complete shipping and fulfillment management system for Sinotrans Logistics, a platform built to simplify and automate logistics for small-to-medium sized eCommerce businesses.

The project was implemented in CodeIgniter (CI) and designed to seamlessly integrate with major online marketplaces and platforms including Shopify, Magento, eBay, Etsy, BigCommerce, Volusion, Zibbett, and PrestaShop.

Key features include:

End-to-end shipping automation – batch shipments, auto-label creation, and customs form generation without copy-paste.

Real-time tracking system – improved customer experience with secure and transparent shipment tracking.

Smart automation – reduced manual effort by auto-filling shipment details directly from eCommerce orders.

Merchant dashboard (CMS) – business owners can manage shipments, fulfillment, and reports in one place.

Scalable architecture – designed in CodeIgniter with MySQL to handle growing business data and high-volume transactions.
