Don't think HRs will look much on LI, it is not mandatory to keep it stuffed. Keep some keywords which match with your target role. When recruiters find you by LI keywords anyway they will ask you to send them CV by email. If possible avoid reaching to company by HR. First find someone you may know who works there. Check if company takes part in some meetups etc, talk with technical people first - they need you.
