I’m a Frontend Developer with 1+ year of experience building scalable, production-grade web applications using React.js and Next.js. I focus on reusable component architectures, clean state management, and maintainable UI engineering.

I’ve delivered measurable performance and quality improvements, including 30% faster load times and a 35% reduction in technical debt. By adopting SSR/SSG, optimizing assets, and enforcing structured code reviews with ESLint and SonarQube, I strengthen Core Web Vitals and long-term code health.

Security and reliability are central to how I build: I’ve implemented JWT-based authentication, cookie management, RBAC, and CSP policies. I also create responsive, accessible interfaces with cross-browser compatibility and strong validation/error-handling patterns.

In key projects like the Zunoy Public Website, Zunoy Admin Portal, and an HRMS web application, I shipped SEO-focused marketing experiences, scalable admin dashboards, and employer/employee workflows with role-based access and efficient rendering.
