  • Build Tools Expertise: Work with modern frontend build tools such as Webpack, Babel, and others to streamline asset management, bundling, and build optimizations.
  • Testing Frameworks: Write unit and integration tests using frameworks like Jest, React Testing Library, and Cypress to ensure component reliability and functionality.

Collaboration & Mentorship:

  • Cross-Team Collaboration: Collaborate effectively with product managers, backend developers, and designers to align on requirements, technical decisions, and project goals.
  • Mentorship: Provide mentorship to junior developers, sharing best practices, offering code reviews, and helping them grow within the team.
