What I'm looking for

I am looking for a role that fosters collaboration and innovation, where I can contribute to impactful projects and continue to grow my skills in front-end development and UI/UX design.

I am a front-end developer with over 4 years of experience in building responsive and high-performance web applications using React.js. My expertise lies in creating modular and reusable components that enhance development speed and maintainability. I have a strong focus on optimizing user experiences through fluid and intuitive UI/UX design practices, ensuring that every application I work on is not only functional but also user-friendly.

Throughout my career, I have successfully collaborated with cross-functional teams, including design, development, and testing, to drive measurable outcomes. My experience includes leading projects that have significantly improved efficiency and user engagement. For instance, during my time at Infosys Limited, I developed reusable React.js components that increased UI development efficiency by 20% and integrated secure authentication flows that enhanced application security. I am passionate about leveraging modern front-end tools and methodologies to deliver exceptional web applications.
