LinkedIn Profile Job Search Optimization

I want to turn my LinkedIn presence for the name “David Castro” into a powerful, job-winning asset. Everything is in place for a basic account, but it lacks the polish, strategic wording, and visual consistency that recruiters expect.

Here is what I need from you:
• Refresh the headline, “About” summary, experience descriptions, and skills so they are keyword-rich and easy to scan for Applicant Tracking Systems.
• Advise on an eye-catching banner image and a professional profile photo style that fit a cohesive personal brand.
• Reorder and fine-tune accomplishments, recommendations, and featured media to highlight my strongest achievements first.
• Provide a short posting calendar (one month, weekly cadence) with post ideas that position me as a knowledgeable professional and keep the profile active.

I will supply my current résumé, existing LinkedIn URL, and any additional background you need. The finished profile should read naturally, showcase measurable results, and make recruiters confident that I am the right hire.
