What's the most important thing to highlight in my resume as a mid-level backend developer?

How do I make my resume stand out from all the other backend devs applying for the same job?
You're gonna need to showcase your experience with databases, APIs, and cloud platforms. If you've worked with AWS or Azure, make sure that's front and center.
What if I don't have direct experience with the specific tech stack the company is using?
Don't sweat it - you can still get hired if you've got transferable skills. Just be honest about what you know and what you don't, and show that you're eager to learn.
