- Implement pixel-perfect UIs from design mockups and wireframes, ensuring cross-browser compatibility and optimal performance.
- Design and build intuitive user interfaces for modern applications that interact with LLM-powered solutions, including chat interfaces, data visualization, and interactive AI outputs.
- Work closely with product managers, UX/UI designers, and other stakeholders to understand requirements and translate them into technical specifications and elegant user experiences.
- Ensure application scalability, security, and maintainability by adhering to coding standards, performing code reviews, and contributing to architectural discussions.
- Implement and maintain unit, integration, and end-to-end tests to ensure the reliability and quality of the applications.
- Optimize front-end performance for speed and responsiveness, addressing issues like load times, rendering, and interactivity.
- Stay up-to-date with emerging front-end technologies, React.js advancements, and best practices in UI/UX design.
- Participate in the entire software development lifecycle, from concept and design to testing and deployment.
