  • Lead the implementation of responsive layouts across desktop, tablet, and shop-floor devices.
  • Identify, analyze, and proactively address performance challenges, especially when working with large data sets and real-time updates.
  • Diagnose and resolve complex UI issues related to state management, rendering behavior, and performance optimization.
  • Ensure a high standard of code quality, including maintainability, readability, and appropriate test coverage.
  • Proactively document technical decisions, patterns, and trade-offs to support long-term maintainability and onboarding.
  • Collaborate closely with product, backend, and UX teams, influencing implementation approaches and technical solutions.
  • Actively participate in planning, code reviews, and technical discussions, providing constructive feedback and guidance.
  • Support other developers through collaboration and informal mentoring, fostering a strong, non-siloed engineering culture.
