I’m a Frontend Developer with 3.9 years of experience building responsive, high-performance web applications. I focus on component-based UI development, clean SPA architecture, and secure REST API integration—so the interfaces I ship are fast, accessible, and reliable.

In my current role as Senior System Engineer - Frontend Developer at Infosys (Pune), I developed and maintained UI for banking applications using React.js and Polymer.js. I ensured responsive design, secure REST API integration, and adherence to WCAG guidelines to improve accessibility, while also reducing release bugs by 35% through code reviews and stronger coding standards.

I’ve consistently improved performance by implementing caching strategies, optimizing data handling with lazy loading, and reducing unnecessary work. On production delivery, I led end-to-end feature execution—partnering with onsite clients, handling production support, and resolving real-time issues to keep releases on track.

Across projects—including a secure internet banking application—I built reusable components using React Hooks, and I optimized async data fetching and API handling. I also mitigated XSS vulnerabilities in an Agile environment, and for Polymer.js initiatives I delivered high-performance banking UIs with code splitting, caching, and fewer redundant network calls.
