I personally have been working professionally since the mid 90s. But I realize that no one cares about the fact that I did C on DEC VAX and Stratus VOS mainframes in the 90s, VB6 in the early 2000s along with C, C++/MFC/DCOM or C# for ruggedized Windows mobile devices in the late 200x. I’ve cut out everything on my resume before 2012.
Your resume is full of responsibilities. But not accomplishments. If I were to ask you why should I hire you over the dozens of other generic developers who run across my desk, what about your career sets you apart? I’m being completely hypothetical. I’m not in a hiring position and I’ve only been in one for a brief stint in my career. But put yourself in hiring manager’s shoes. Why would you hire you?
I’m not sitting on high judging you by any means. I’ve had a fairly unremarkable career myself until 2018 and nothing that really stood out.
