- It shows you jumped around too much, and there is just way too much irrelevant information

Agreed, some of those could be dropped. But some of those are internships or short contracts, I don't see a reason to remove all of those necessarily

- Blog/Hobbies

It's on his personal website, I don't see anything wrong with it. It shows that he's passionate about tech, he wouldn't just be some random work monkey if he got hired. Most of his posts are about tinkering with things. Looks like a standard blog to me. I saw your blog, and it definitely reads way more like a journal than his, which is good because it conveys your personality and that you have opinions (confidence)

- "• Entrepreneurship: Buying, refurbishing and reselling a class set of iBooks in 2005; iPod repair at ", " Took online training courses in big data processing with ElasticSearch and Tensorfow machine learning. ",...etc → it shows you think a bit too highly of yourself, ego might be an issue

I'd say this falls more into the 'irrelevant' category. His website or resume doesn't give me the impression of ego, if anything it gives the opposite impression: that he's a little shy, maybe desperate, and maybe thinks too little of himself

There are really two key issues I see standing out by looking at his profile:

1. Non-comittal, he's moved to a lot of different places. While his portfolio shows that he's intellectually curious, it also shows that he isn't taking career as seriously as he should. All of those internships and none of them progressed into a job? That's a red flag for sure. Maybe this is what you're sensing. Get rid of this. Showing that you've travelled a lot and only worked short periods does not send out a good signal

Also this coupled with the hobbyist impression on the website might be even more of a red flag. You have intrinsic interest in a lot of tech but you're professional side doesn't reflect that. Do you hate business? it kind of implies that you aren't very business-oriented. If so, maybe think about grad school and going into academia, just my 2c

2. He might be a little too introverted and shy, and should probably take more initiative to network and meet people. Jobs are a seller's market, companies get tons of spammed applications that barely get read. Networking helps a lot
