No great company name. No special univerity. Starting with a slight handicap here.

Intro is too long. Make it shorter and to the point. After 5 or 10 lines, it get hidden automatically.

[Do you realize that you have the equivalent of "I am open totally to leave my current company" while you're working at your current company?]

You lack a lot of keywords. Only Python, DynamoDb, AWS. You must have touched other things. The titles are 4 times "software engineer [intern]". You NEED MORE KEYWORDS.

The short line on each company is good and well written, I love to get context. =)

The content is missing substance. Add business metrics, how many users? how many servers? how many dollars going through? how many mails send [at the mail company]?

Yeah. Can't do anything about my university or past companies. I do realize I have the equivalent of "I am totally open to leave my current company," because for the right offer, I would. Saying I'm "open to opportunities" means precisely that: offer me something that betters my current and future situation, and I might take it. If a company doesn't understand that, they're deluding themselves.

I have no visibility into these business metrics because they don't tell me.

What type of keywords do you suggest?

The university fades after a bit of experience (and regular switching to better companies :D).

I try but I cannot understand your situation. I couldn't work without business and user metrics. That's the only thing changing from a job to another.

Keywords: More technologies. More trendy job titles. [Don't know what's relevant to your past jobs. Can't help.]

What would be examples of trendy job titles? I can safely and ethically change my previous job title, as long as it doesn't imply I was an executive and accurately represents what I did. (They officially don't care about job titles. It's literally whatever you want as long as you don't claim to be an executive when you're not.)

Believe it or not, changing these job titles to what they are now actually got me far more attention than what I had before (which was just the "official" job title, which didn't necessarily reflect the things I was actually doing).

Software Engineer, Data Engineer, Systems Engineer, Software Architect...

There are endless variations referring to close jobs.

One trick in Linkedin is to update your "Job Title" in your most recent job. That triggers something that premium recruiters can see. I cannot back this with certainty but have seen this work for my own profile a few times.

I'm not sure if it's just your most recent job title or any update that triggers that, but I did get significantly more views when I was actually looking and did trivial updates on my profile every couple of days. I wouldn't necessarily want to signal that I was looking to my current employer or coworkers though. I'm aware you can turn the "notify your network of profile changes" setting off, but I wonder if it's a wise thing to do.

And, all that twiddling of one's profile seems like a stupid thing that I'm reasonably sure people generally don't do. Maybe I just need to write a bot to automate it.

Sigh. I don't know how to LinkedIn. :P
