I’m a frontend engineer who builds scalable, performance-focused web platforms. I developed a large-scale internal research platform supporting 1000+ workflows using React.js and Spring Boot, and I’m comfortable owning UI architecture end-to-end.

At Tata Consultancy Services, I led a team of 6 engineers—handling task allocation and code reviews—while improving sprint delivery efficiency by 20%. I built reusable UI components and optimized the frontend architecture, reducing feature development time by 25%, and implemented performance optimizations like lazy loading and code splitting to improve page load time by 30%.

I also focused on backend-adjacent performance and reliability. I designed and optimized REST APIs to reduce average response time by 40%, scaled systems to handle a 5–10x increase in concurrent users, and debugged production issues to reduce recurring defects by 35%.

In my current role, I’m building a white-label platform for 5+ partner applications using a shared base web shell architecture. I integrate mini-app modules, reduce initial bundle size by 25% with dynamic imports and lazy loading, automate Snyk security checks in CI/CD, and use Splunk to reduce MTTR by 20%.
