What I'm looking for

I am looking for a collaborative environment that values innovation and offers opportunities for growth.

I am a passionate Senior Frontend Developer with over 8 years of experience, specializing in React.js. My expertise lies in building high-performance, scalable, and user-friendly web applications using modern JavaScript frameworks. I possess strong problem-solving skills and a keen eye for design, ensuring seamless user experiences across all devices.

In my recent role at Byjus, I led the development of a Next.js-based dashboard, achieving a remarkable 40% reduction in load times through server-side rendering and static site generation. I also migrated a legacy React codebase from JavaScript to TypeScript, significantly improving code maintainability and reducing runtime errors. My commitment to enhancing application accessibility and mentoring junior developers has been pivotal in fostering a collaborative and high-quality development environment.
