Comprehensive Self-Assessment Builder

Help me write a comprehensive self-assessment for my performance review.

My role: {{JOB_TITLE}}
Review period: {{REVIEW_PERIOD}}
Key responsibilities: {{KEY_RESPONSIBILITIES}}
Major projects completed: {{MAJOR_PROJECTS}}
Goals from last review: {{PREVIOUS_GOALS}}
Challenges faced: {{CHALLENGES}}
Skills developed: {{NEW_SKILLS}}

Please create a well-structured self-assessment that:
1. Summarizes my key accomplishments with specific metrics where possible
2. Addresses how I met or exceeded my previous goals
3. Honestly discusses challenges and how I overcame them
4. Highlights professional growth and new skills acquired
5. Demonstrates alignment with company values
6. Sets the stage for discussing future development

Use a professional but authentic tone that showcases my contributions without being boastful.
