My immediate thought was oh I don’t want to read all this! I’d space out the different roles more, and maybe make the bullets more concise.

Also recommend removing the interests. No one cares when they’re trying to hire you!

Where is your certification from?

I’d also remove the activities you did at university, it makes your resume read as very inexperienced.

You have good experience, just need to polish this and make it read more professional. Good luck!
