- Show progression and growing responsibility
- Include metrics that matter to the business
- Demonstrate collaboration and team contribution
- Less emphasis on school projects
- More emphasis on professional accomplishments

EXPERIENCE SECTION STRUCTURE:
- Group related achievements under subheadings for readability
- Use subheadings like "Performance," "Feature Development," "Code Quality"
- This prevents dense blocks of bullets
- Include 8-10 bullets for current role
- Include 5-7 bullets for previous roles
- Condense older roles to 3-4 bullets

KEY METRICS FOR MID-LEVEL ENGINEERS:

Performance Metrics:
- Response time improvements (ms to ms)

- Daily active users (DAU)
- Requests handled per day/second
- Data volume processed
- Concurrent users supported

Reliability Metrics:
- Uptime percentages (99.9%, 99.99%)
- Bug reduction percentages
- Test coverage improvements
- Mean time to recovery (MTTR)
- Error rate reductions

Business Impact Metrics:
