I’m a Full Stack Developer specializing in the MERN stack, with hands-on experience building scalable production systems serving 5K+ users. I focus on real-time system design, AWS infrastructure, and performance optimization to deliver reliable user experiences.

At Connectia Technology, I engineered Carat Years, a real-time diamond factory ERP with an auto-pricing engine driven by external APIs—eliminating manual price updates and improving accuracy. I also built a high-volume Excel-to-JSON pipeline (500+ records per upload, up to 150 products per batch) with validation, transformation, and error reporting, while delivering frontend performance improvements.

I led an AWS cloud migration with zero downtime to keep production availability uninterrupted. For NBTC Multi-Site CMS, I enabled a no-code, template-driven platform managing 8 websites, implemented Redux for centralized state, removed redundant API calls, and added lazy loading to reduce unnecessary re-renders and improve page load time by ~35–45%.

I’ve built event-driven, real-time experiences as well—LezzGo handles 5K+ active users with live location tracking and Socket.io communication. Earlier, as a Full Stack Intern, I launched TradeShow with live streaming visuals, dynamic banners, targeted in-app promotions, and AWS OBS integration using React, Node.js, and Express.js.
