Return to Origin (RTO) costs are the silent killers of e-commerce profitability. High shipping costs on returned items can wipe out a seller's margins before they even realize it.

The Solution: A reactive, entirely client-side simulation engine that lets sellers input their data, visualize hidden fee structures dynamically, and export instant PDF reports.

The Tech: React, Chart.js, jsPDF.

The Result: Zero server overhead. A lightweight frontend tool that has helped clients pinpoint leaks and save up to ₹25,000 monthly.

If you sell the same inventory on Amazon, Shopify, and your own custom site, keeping stock levels synced is a nightmare. Overselling leads to canceled orders, angry customers, and penalized seller accounts.

The Solution: A centralized inventory hub that uses parallel processing to broadcast stock updates simultaneously to multiple storefronts the second a purchase is made.

The Tech: MERN Stack (MongoDB, Express.js, React, Node.js).

The Result: Real-time stock synchronization across all connected channels in under 1.5 seconds.

Handling logistics manually is a fast track to human error and delayed shipments. I wanted to build a system that completely eliminates manual data entry while maintaining blazing-fast performance.

The Solution: An automated order synchronization system built on top of Express.js webhooks. It listens for order updates and immediately pushes them to the Shiprocket logistics ecosystem.

The Tech: Node.js, Express.js, Shiprocket API.

The Result: Achieved sub-2s latency for end-to-end sync, removing the need for manual tracking entirely.
