What I'm looking for

I am looking for a role that fosters innovation and collaboration, where I can leverage my front-end skills to create impactful user experiences while growing professionally.

I am a front-end enthusiast with nearly 4 years of experience in creating responsive user-centric interfaces. My proficiency in JavaScript and TypeScript, along with expertise in frameworks like React and Angular, allows me to build reusable components that deliver seamless functionality across all major browsers.

At ZS Associates, I have successfully engineered high-performance web components and optimized user interfaces as part of the ZS Design System. I am passionate about improving code quality and user experience, having developed comprehensive guidelines for front-end mutation testing and ensuring compliance with accessibility standards. My collaborative approach has enabled me to mentor new team members and foster a culture of excellence in front-end development.
