I’m a Senior Frontend Engineer with expertise in React.js and JavaScript, focused on building scalable, high-performance web applications that are production-ready. I take ownership of system design and frontend architecture to improve stability and reduce operational issues.

At FabHotels & Travelplus, I led the end-to-end development of the Cab CRS (Central Reservation System) from scratch to production, delivering a scalable and fault-tolerant architecture. I improved overall application stability and reduced production issues by ~35%, led and mentored a team of 4–6 engineers, and implemented a Microfrontend architecture that enabled independent deployments and reduced release cycle time by ~40%. I also optimized hotel and flight search logic to reduce search response time and implemented Server-Sent Events (SSE) for real-time flight search updates, enabling results within the first 1–2 seconds.

Previously, I developed end-to-end flight and bus booking flows, including search results, seat selection, checkout with integrated payment, and confirmation screens—built for usability and performance. I also created a scalable expense management system for automated tracking and approvals, integrated crash analytics (via Microsoft Clarity through Google Tag Manager), and designed a reusable component library from scratch based on the organization’s design system. Earlier, as an R&D Intern at Hewlett Packard Enterprise, I built a dashboard to visualize security vulnerabilities across 400+ products and developed Python scripts to aggregate data from multiple APIs for frontend integration.
