Write a LinkedIn About Section That Converts Visitors

Act as a LinkedIn copywriter. My current About section is: [CURRENT_ABOUT]. I am a [PROFESSIONAL_TITLE] who helps [TARGET_AUDIENCE] achieve [SPECIFIC_OUTCOME]. Rewrite my About section using this structure: a 2-sentence hook in first person that leads with impact not title, a paragraph on what I do and who I help, a paragraph on my background and what makes my approach unique, a short proof point (achievement or result), and a clear call to action at the end. Maximum 300 words. No third person. No buzzwords.
