India

Message

At Paytm, I architected and deployed two Module Federation micro-frontends for a platform serving 100K+ daily active users, reducing bundle size by 30%. I also delivered six core platform features and reached 100% unit test coverage and a 95+ Lighthouse score.

At Teemuno (gimmefy AI), I built the frontend of AI-powered image and video editing tools and developed a reusable component system for 150+ automated marketing tasks and assistants. I implemented Redux Toolkit, improving client-side render speed by 25%.

At Collaberus Technologies Pvt. Ltd., I owned frontend development for three SaaS products and built portals with real-time WebSocket updates. I also integrated browser-based VoIP calling with JsSIP; earlier, at VDK Eduventures Pvt. Ltd. (Drishti IAS), I improved UI responsiveness and API handling.
