- Conduct cross-browser and cross-device testing to guarantee consistent, accessible, and high-quality user experiences across all major browsers, operating systems, and screen sizes.
Integration, Code Quality & Collaboration
- Integrate frontend applications with backend APIs and data services — working closely with backend engineers to build seamless, performant data connections and ensure a robust full-stack experience.
- Participate in code reviews and enforce frontend development best practices — including component reusability, code maintainability, clean architecture, and documentation standards across the development team.
