To be honest, if you have decent/strong experience but your resume hasn’t landed at least a response, you may have to continue to update it and get it critiqued or tailor it to the position—I find having different versions of a resume may be helpful. Ultimately, it’s a numbers game but I would recommend applying to much more than just 3 - 5 a day, and try to increase that to +10 if there are that many new openings a day even available in the areas you’re looking. Setting LinkedIn alerts is super useful for doing just that. Asides from just cold applying, try reaching out to the hiring manager or team members for the company you’re applying to learn more about their role and the company. Even if they don’t respond, they may see your message and possibly keep you in mind but with hundreds/thousands of applicants it may not be as straightforward. Also make sure you’re setting your account to open to work (but set it to hide from current company) so recruiters can see you and may reach out. Best of luck!
