• Promote Test-Driven Development (TDD) and Behavior-Driven Development (BDD) where appropriate.

• Ensure the performance, reliability, and maintainability of frontend applications.

4. UX, Design System & User Experience

• Work closely with Product teams to challenge and improve UX decisions.

• Ensure accessibility, performance, and visual consistency across applications.
