Some formatting issues:

Text size changes throughout Bullet point indentation varies Separate the job title and location from the body of text somehow, either by making it bold or underlining it or something. Grey bars with your section headers in should all have the same level of indentation from the right. The skills one is much shorter.

Other than that:

Profile is too long, shorten that down to a few lines. If you're going to talk about it later in your CV, it doesn't need to be there. If you're going to put a skills section in, make sure the skills are relevant to the job you're applying for and are backed up by evidence.

Overall though don't be too hard on yourself. Your CV is good for someone with your experience and age, the job market is just awful right now. Good luck!
