A deep-dive look at the design, architecture, and performance outcomes of major web applications I have led and engineered.
Infosys Energy Management System
A real-time energy monitoring dashboard designed for industrial clients to track power grids, carbon footprints, and consumption anomalies.
THE CHALLENGE
Large volumes of streaming analytics data caused heavy browser rendering pipelines, slowing down dashboard loads and causing interface stuttering.
THE SOLUTION
Engineered a dynamic Chart.js analytics engine combined with a React Query caching strategy, implementing component-level lazy loading and memoized data handlers.

Global E-Commerce Platform
A highly modular, responsive e-commerce infrastructure supporting rapid checkouts, dynamic filters, and real-time inventory checks.
THE CHALLENGE
Legacy checkout funnels suffered from cart synchronisation drops, unoptimized image sizes, and heavy re-rendering during product filter selections.
THE SOLUTION
Created a React e-commerce framework powered by Redux Toolkit for state tracking, memoized selectors to block unwanted re-renders, and integrated lazy-loaded routes.
