👩🏻‍💻 Front-End Developer

I’m a Front-End Developer with a background in technical support, project management, and client relations. These roles strengthened my problem-solving skills, adaptability, and ability to communicate effectively across technical and non-technical teams. I now apply these strengths to building accessible, user-friendly websites.

I make it a priority to stay informed about industry trends, continuously refining my approach to front-end development and user experience. I have a strong interest in UX, ensuring every site I create is visually engaging, intuitive, and inclusive.

I’m also expanding my expertise in React and web accessibility while exploring Python and prompt engineering to broaden my technical scope.
I thrive in collaborative teams where I can contribute, grow, and build meaningful digital experiences. I'm eager to apply my skills to impactful projects and open to new opportunities where I can make a difference.
