Review a senior backend engineer's career materials for the US remote market (30-45 min)

I am a senior backend and AI engineer applying to remote roles at US companies. I want an honest outside read on how my professional materials land with a US audience.

I will send you the materials privately in this bounty's chat after I accept your application. Nothing personal is posted publicly on this listing.

Spend 30 to 45 minutes and send back written feedback covering these six points, in order:

1. First impression. After 15 seconds on the headline and summary, what do you think I do, and what seniority do you read me as?
2. Headline. Does it work for US remote senior backend and AI engineering roles? Give one or two concrete rewrites.
3. Summary section. What is unclear, too long, or generic? Name the sentences you would cut.
4. Experience. Do the role descriptions read as credible and specific, or vague? Name the single weakest bullet and say why.
5. Red flags. Anything that would make a US recruiter hesitate, including wording that reads as non-native English or AI-generated.
6. Top three changes, in priority order.

Be blunt. Generic praise is not useful to me. I am paying for the parts that are not working.
