Collaboration & Leadership

  • Partner with backend engineers to integrate with RESTful APIs and scalable services.
  • Explain technical solutions clearly and troubleshoot independently without over-reliance on AI or external tools.
  • Contribute to technical decision-making, recommending React vs Angular trade-offs when appropriate.
  • Mentor junior engineers in frontend best practices.

Observability & Performance

  • Monitor and analyse frontend performance with Lighthouse, Core Web Vitals, and React DevTools/Angular DevTools.
  • Optimise React and Angular applications for speed, performance, and high availability.
