About

Frontend Engineer focused on building high-performance consumer applications at scale. Currently working on a product with 100M+ downloads and 60M+ monthly active users, contributing to a widget-based dynamic homepage rendered inside a cross-platform webview. My work centers on performance optimization, scalable UI architecture, and production reliability. Improved Core Web Vitals by reducing LCP from 3.5s to 600ms (~83%) using lazy loading, initializer tuning, image optimization, and Webpack tuning. Implemented analytics instrumentation with Google Analytics and CleverTap to enable user journey tracking and product insights. I enjoy diagnosing complex production issues — from browser compatibility and rendering defects to real-world performance bottlenecks. I regularly collaborate with product, design, and backend teams, conduct code reviews, and mentor junior developers. Tech focus: React, Angular, JavaScript (ES6+), Web Performance, Core Web Vitals, Webpack, HTML5, CSS3, Chrome DevTools, Lighthouse, Google Analytics, CleverTap. Previously worked with Node.js and AWS, giving me a practical understanding of system behavior across the stack. Interested in product companies building large-scale platforms, performance-critical systems, and user-centric experiences.
