Senior Frontend Engineer
As a Senior Frontend Engineer at BJS Soft Solutions, I led the development of multiple production-ready applications using React.js and Next.js. My work focused on building scalable UI architectures, implementing Redux-based state management, and optimizing performance — achieving a 30% improvement in page load times. I collaborated closely with backend teams to design REST APIs and ensure seamless data integration, while mentoring junior developers to improve overall code quality and workflow efficiency.
Next.js Developer (Part-Time)
At React-ive Code Labs, I am working as a Next.js Developer where I am responsible for building and maintaining a multi-tenant web application. My work includes implementing modern UI designs, integrating APIs using TanStack Query for efficient data fetching and caching, and ensuring scalable architecture to support multiple tenants seamlessly. I also focus on optimizing performance, maintaining responsive layouts, and delivering a smooth user experience across devices.
