Ensure cross-browser compatibility and resolve front-end performance issues.
Conduct testing and debugging to improve usability.
Stay up to date with emerging front-end technologies and best practices.
Skills and Qualifications:

Strong proficiency in JavaScript and modern frameworks/libraries (e.g., ReactJS, AngularJS, Vue.js, etc.).
Experience with client-side scripting and JavaScript frameworks, including jQuery.
Basic understanding of server-side CSS pre-processing platforms such as LESS or SASS.
Good understanding of asynchronous request handling, AJAX, and RESTful APIs.
Proficient understanding of cross-browser compatibility issues and how to resolve them.
