  • Own and lead the development of complex UI features and platform components using TypeScript and React

  • Contribute to full-stack features using Node.js when needed

  • Collaborate with other engineers to design scalable and performant solutions

  • Optimize for cross-browser compatibility and responsive UI

  • Participate in code reviews, architecture discussions, and continuous improvement
