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.

Throughout my career, I have successfully developed responsive web applications from scratch, collaborating closely with UI/UX designers to ensure design fidelity and user experience consistency. My recent projects include a logistics platform and a crypto exchange site, where I implemented performance optimization and accessibility standards. I am passionate about leveraging technology to create user-friendly applications that meet business needs.
