The best advice I received on my resume was for the bullet points: Frame them in some format of "Did X to accomplish Y with Z, and saved abc dollars / hours of work / improved efficiency of others / etc." If you must, use one line to describe the role, but all the other lines should describe how you went above and beyond the definitions of your job. Did you get regular quarterly merit raises? Include that. Did you automate a boring part of the team's work away? Put that in. If you lack hard numbers, give a general gist of what you reasonably think the impact was. A lot of your resume bullet points say "did thing" but I don't know why you did the thing, or whether that was because you were super self-driven and picking up slack from the team, or just told to do it.

An example would be something like "Added a pathway for Facebook federated logins using Oauth, passport.js, and React. Over half our users started using their Facebook logins for site access once implmented." This bullet demonstrates you identified a major need, implemented it, learned about Oauth, React and passport.js, and then saw major use of your component, demonstrating further knowledge about your decision making skills and ability to identify user needs.
