- Highlight component reuse to prove you value scalable and maintainable UI patterns.
- Showcase technical migrations to demonstrate initiative in improving codebase health and reliability.
Common mistakes
- Focusing only on 'learning' instead of 'delivering' which can make you seem like a student rather than a professional.
